Disagree. I have gripes with my country right now, but it's impossible to ignore how much easier to make and save a lot of money here in the US compared to other places.

First, it's so easy to start a business in the US.

$1000 (maybe less?) gets you an LLC or an S-Corp, properly done with an accountant. $200/mo gets you a virtual office or a coworking space. Tax code is also friendly to small businesses. Healthcare is the only disadvantage, though you can get on group plans to work around that.

If you have an idea, it's easy (well, easier) to scale it in the US.

Actually, going back to taxes. Tax in the US is CHEAP compared to other developed countries. I met someone from Denmark some time ago that told my wife and I that they left to escape 50% taxes. Here, the worst you'll do is ~38%, federal, state and city combined. This means that you can make great money as a worker bee depending on the industry.

All of this is a major reason why so many people all over the world come to the US, make their money (with enough to send to family back home) and move back.
