I at least read the article I linked to, so I’ve put up more effort than yourself.
You wanted to know why countries subsidize, and I gave you an article explaining some reasons why we do it.
The shortest answer is that countries want these businesses to thrive in their country, so they prop them up with subsidies. We do it, almost every country does it. I don’t personally agree with it as a fiscal conservative, but I accept the reality of it.
That said, do you agree we should drop all subsidies that protect US interests?
Both are a form of protectionism. One makes buying foreign goods more costly, which is supposed to incentivize the purchasing of domestic alternatives that might cost more without the tariffs. The other assures that a business will still have a source of income should they be unable to sell their goods on the free market, or to boost income to help a business thrive.
As you might have noted in the trade war thread, the price of domestic steel increased with the tariffs. So now all steel costs more, not just the foreign steel. I predicted as much. The only winners in that are the government (tariffs) and the domestic steel mills (increased profits). All consumers of steel lose.
Only Trump sycophants think that trade deficits are fundamentally bad, because dear leader said so; it can make you sound tough and frame everyone as “winners and losers”.
Johnny buys more apples from Bob, than Bob buys diamonds from Johnny, because Bob is a poor dude just making ends meat. Not to mention Johnny really only sells financial consulting services anyway. Johnny has a trade deficit with Bob… OH NO… TIME FOR A TRADE WAR!
Negative trade deficits for the USA are really an indicator of wealth and consumption.
