Of course since I'm just a nobody on a forum what do I know.
It depends on what you mean by rich. From a GDP PPP perspective there are issues on short, medium and long term when compared with other countries. For example: China is richer than the whole of the EU (incl UK). US is almost as rich as the EU. India is 1/2 and Japan 1/4.
*By rich I mean GDP PPP.
Not only does the US have about ~40% of all the millionaires on earth all by itself, its GDP per capita is 77% higher than the EU ($33,700 per capita per the Worldbank 2017 figures; versus $59,700 that year for the US). Its nominal GDP is also about $2 trillion higher, despite having roughly 200 million fewer people.
PPP is a near worthless measurement if you're a business trying to sell goods. It's the absolute last thing you'd rely on to gauge the pricing power in a market for a product or service.
but I agree with you that from a business perspective the US is de facto the place to be.
Oi! Ireland and Malta would have a word with you, mate.

Not the biggest, but the richest.
