While it's an upheaval to be sure, the vast majority of these laid-off employees have in-demand skills in a growing industry. Who I really feel for is people who get laid off in shrinking industries, where it's basically a game of musical chairs and there are fewer seats each round.

The reason why is be because starting a company in America is generally a good idea

Leaving off energy companies, 9 out of the top 16 companies are American.

4.5% of the world's population, ~55% of the world's great companies.

I'm sure at will employment alone wouldn't crush the American economy. But it'd be a hit to it.
