They don’t leave America if it means they can no longer do business here,
Business‘ jump through a lot more hoops and pay a lot more taxes to do business in mexico and China. Or, you have to manufacture in China if you want to sell in China.
Comparing us to a Communist country is not very convincing. Yes, businesses wouldn't leave if they couldn't sell here. But in a free country, they can. Correct, other places do have higher taxes thanks to President Trump, but other expenses have to be considered as well: labor costs, workman's comp insurance, healthcare, unemployment insurance, matching employees Medicare and Social Securty contributions, business regulations, holiday pay, all of which companies in other countries don't have to deal with.
While there is little we can do about that situation, what we can do keep their tax rate as low as possible to keep them here, and we have done that.
If Biden does get into the White House (it looks like he will), and the Republicans can't hold on to the Senate, the job loss will dramatically increase. Higher taxes on our businesses, higher taxes on wealthy people, a national $15.00 an hour minimum wage which will set off a domino effect causing wages to artificially increase across the board will certainly chase them out of the country. And then we want to free daycare, job training, college to the mix to tax them even more?
