The United States of America is a federal republic made up of 50 states, five significant territories which are self-governing, and a federal district. It is currently the largest capitalist mixed economy on the globe (World Bank. 2018, p.1). According to the World Bank, it has a nominal GDP of $18.45 trillion, a 3% GDP growth per annum and an unemployment rate of only 4%, making it one of the lowest on Earth. A large portion of its population can provide their families with basic needs as needed. In addition to that, the USA boasts a 24% stake of the gross world product and a trade deficit worth $635 billion, according to a 2010 survey by the UN Data (World Bank. 2018, p.1). This prosperity draws people from all around the globe who dream to migrate into the country in search for better lives.

Besides that, the United States ‘largest import commodity is oil, while its largest export is transportation equipment such as automobiles, airplanes and fighter jets (Plummer, and Tonts, 2015, p. 7). Interestingly, the country has a robust private sector, which contributes to approximately 86.4% of the economy. Among the important sectors in the nation is the energy sector, where it boasts of hydro-electric power, diesel engines and nuclear power. Nuclear power is not only in the electrification efforts but also for powering assets such as ships and submarines. It also has the highest number of nuclear warheads on the globe; hence its wishes and preference are respected as well as remaining a military fortress. Above all that, it had a Foreign Direct Investment of $47,465 million, scattered across different parts of the globe (World Bank. 2018, p.1).

Among the most impressive factors about the Untitled States of America is the continued growth in the nation’s FDI over a short period. With an average of US $24,294.82 million since 1994, the fourth quarter of 2017 saw it skyrocket to the current US $47465 million (IMF. 2017, p.2). This is more impressive than many other nations, bearing in mind that it has not engaged with other countries as much as China. It has also managed to nurture and incubate the spirit of entrepreneurship, seeing that 86% of its economy depends on it (IMF. 2017, p.2). This vividly shows that the children are brought up focused on coming into this world and causing a different rather than joining the “employment hunting teams” available in many other nations (Plummer, and Tonts, 2015, p. 7). Besides being one of the largest oil importers on the globe, the US also has its oil reserves, which it preserves for future uses while utilizing that found in other nations such as the Middle East (World Bank. 2018, p.2). This is being smart.

The US is renowned around the globe for its infrastructure. According to the World Bank, it boasts of a total of 4 million miles of tarmacked road that surpass around the nation. It has iconic buildings such as the World Trade Centre which used to hold the title of tallest structure until recently. It also spends about $600 on the military budget (IMF. 2017, p.2). Other elements include countless skyscrapers dotting the skies of major cities, airfields, healthcare institutions and sports facilities. Besides making the nation a significant tourist center, these developments have established it as a sports hub for various sports such as Automobile racing. It has also invested in other important areas such as research, agriculture, space exploration and trade, making it a monumental name in most affairs around the globe.

The United States of America has capitalized on various factors which make it stand out as the superpower and the most significant economy it is. The infrastructure, military and other factors that power the nation such as water, electricity, ethnic diversity and unity enable it to remain in its current position as the unshaken most significant power (Plummer, and Tonts, 2015, p. 7). Besides being a healthy economy, it is impressive how this continues to grow every year strengthening its global command. The USA is a Superpower. There is greater potential for growth the US due to the high number of graduates and other professionals from around the globe seeking to migrate and launch their careers in the nation. It remains dear to a large portion of the world population, hence; its power and dominance on the globe continue to grow consistently.

Australia is a continent nation on the southern part of the globe, and the World’s sixth largest country by area. It is a peaceful and stable liberal democratic nation made up of six states and some territories. According to the IMF, it is the 13th largest economy, with a GDP of US $49,882 per capita, thanks to its low population (24,866,800). The nominal GDP of Australia totals up to US$1.39 trillion (Plummer, and Tonts, 2015, p. 7). It has a reasonably strong army, as it has the 12th largest military spending on the globe. This army has been assisting other great armies in various wars such as Afghanistan and Iraq. It has a vast wealth of minerals and a relatively low rate of poverty relative to other developed nations in its class. These are extracted for markets all around the globe, especially the US. According to the UN Data, the country ranked second in the world after Switzerland regarding average wealth. This means that most people in the nation have comfortable living and a significant percentage belong to the middle class (Plummer, and Tonts, 2015, p. 7). Another very impressive fact about this nation is that all its cities are rated highly in the global comparative livability surveys. This makes many people desire to travel, live, work and even belong to Australia. It was also among the global economies that did not experience the rough side of the 2008-2009 global recession and financial downturn (Plummer, and Tonts, 2015, p. 4). It has an unemployment rate of 5.1%.

Australia is a developed nation which continues to grow gradually amidst many challenges along its course. It has vast stretches of deserts and inhabitable land, where water is scarce hence development is scanty as well (Plummer, and Tonts, 2015, p. 7). Due to this, infrastructure is not as beautifully developed as it is in many nations of its class. It is impressive how safe the country remains against terrorism and related activities. Its military is among the most robust on the globe, with its presence being recognized amidst that of the US and other powers such as Canada. It exports minerals, telecommunication materials and has been creating itself as a major tourist and sporting center, attracting participants from across the globe. This has also been facilitated by its sound relationship with other hands with whom it has established bilateral and multilateral agreements for trade, business, work, and residence.

Australia is developing rapidly developing nation fuelled by abundant resources especially minerals, land and renewable energy such as sun and wind. It has developed its cities in an impressive way to attract global traffic into the fields of entertainment, education and even residence. The World Bank argues that Australia has been through challenging times, considering its GDP growth curve in the recent years (Plummer, and Tonts, 2015, p. 9). However, with the current investments and other measures put in place, this development is about to take off at a pace never witnessed before. Significant portions of people from other parts of the world are shifting to the nation, promoting its growth over time. However, I think leadership in Australia is of limited scope development wise, compared to other countries such as China and Canada. The leaders should be more focused on utilizing the available resources to transform the continent nation further and ensure that it captures worldly attention.
