America is the greatest nation that currently exists

First off, thanks for defining the argument so concisely. Now to continue, let's examine the parameters of the argument and why they are false.Prosperity - many countries are vastly more prosperous. Marketwatch says most Americans are one paycheck away from the street (www.marketwatch.com/story/most-americans-are-one-paycheck-away-from-the-street-2015-01-07). Huffington Post says almost 50% of working, gainfully productive American families are one crisis away from abject poverty (http://www.huffingtonpost.com....)I live here in Malaysia, a third world (or more accurately, second world) country and there are almost no homeless people here. A minimum wage worker actually can have savings if he (or she) wants to. I have to admit that people work hard here, but Americans work just as hard. If you just keep your money in a bank fixed deposit (analogous to Time Deposits and Certificates of Deposit) you'll get a return of 4.1%, which is way above anything an American bank will ever offer you. It's also safer - it's guaranteed by the government of Malaysia (rated A-3 by Moody's, A- (long term)/A-2 (short term) by S&P, and A- by Fitch) and no bank has ever failed in this country. This compares favorably with the US, in which so many banks have failed there's actually a permanent list at https://www.fdic.gov... .Taxes are low. If an individual holds real estate for more than five years, the capital gains tax rate is zero. All capital gains accrued by individuals after five years are not taxable. There is no inheritance tax here. Dividends payable are not taxed either.Quality of life - We have 14 public holidays a year. These are public holidays, not paid vacation days. Companies usually allocation another 14 days of paid vacation (called "paid leave" here) for a total of 28 days. Your average employee works 9-5 five days a week, and gets almost a month of vacation a year, fully paid (not including sick days.) Healthcare is subsidized, the government pays most of it. If you are "disabled", the government pays all of it. If you are employed, the employer usually has a contract with several healthcare providers, which means your healthcare is fully paid. The weather is mild and tropical. The warm and humid climate means no one ever dies of "exposure". individual freedom - when we talk about freedom here, we usually mean one of two things. The first is freedom to move (personal mobility) ie. how easily can a citizen get from one point to another? towards this end, we actually have three train networks and are building a fourth. We also have extensive bus routes connecting them. From my house, I can walk to a train station and take a comfortable, spacious, quiet, air-conditioned train to a mall over twenty kilometers away, and all it would cost me is fifty US cents. If one prefers to drive or ride a bike, one can do that as well. There are two ride-sharing services operating here (Grab and Uber), as well as taxi services. The second (and arguably the most important one) is personal freedom (as in the right to free speech.) This is well respected here. The prime minister has been roundly roasted for some things he said that the citizens did not take kindly to. For instance, there was one day that he said that food prices were not going up because the price of a vegetable (one vegetable) had remained constant. This was the result of it :https://www.google.com...I'd say the point was made, wouldn't you? :)Economic diversity - we are usually known as an oil-producing country, but we also produce palm oil, rubber, rice, fish and vegetables. In addition, we have a thriving electronics industry, playing host to many global players such as AMD, Intel, Seagate, Samsung and Western Digital. Apart from that, we also have a service industry - AMD also has a global services center here, as does Paypal. There are also local players such as Silterra and Malaysia Microelectronic Solutions (MMS.) The processor you are using in your computer could have been made here.Technology - I'd have to say we import most of it, or rather that we import the people who help us build the technology, which we then run and maintain on our own. Most of the technology here is based off of a design that originated outside the country. I think we saw no real need to reinvent the wheel, when we could see so much further by standing on the shoulders of giants. Military power - this is formidable, but we are not exactly a military superpower. That said, we are surrounded by two closely allied countries and the sea. We are also fortunate to count among our friends the world's top two military superpowers (and perhaps a third as well.)International relations (allies, the UN, etc) - Malaysia is a member of the UN in good standing. Razali Ismail of Malaysia was president of the UN's 51st general assembly (http://www.un.org...). We are allied with pretty much every major country, and several less-major ones. Government stability - The leader of the country has never been assassinated. There are no riots, and the rare blackouts do not result in widespread looting. No government has ever been overthrown by force. Rate of advancement - The Sun says "Malaysia's economy recorded robust growth of 5.6% in the first quarter of this year (1Q17) against the 4.1% registered in the same quarter of 2016, boosted by strong domestic demand and private expenditure." - http://www.thesundaily.my...This compares favorably with the US growth of 0.7% this past quarter (https://www.washingtonpost.com...) despite Trump's promises of growth.That concludes my argument. The facts above clearly demonstrate that America is not the greatest nation that exists, based on the parameters offered. Thank you.
