> if china will do it im pretty sure US economy will take a big hit.

You being "pretty sure" doesn't translate to actual reality. If you followed the events in the real world, you'd know that Samsung workers were about to strike and cripple the company because they were offered only $400K of bonuses per worker, while the workers in the competing (also Korean) SK Hynix were being given a cool $ 1 million.

Your money is going to Korea and Taiwan who charge an arm and a leg and they have absolutely no intention to increase production because they like these prices. The US trade deficit grew because of them, despite tariffs, sanctions and threats.

So, the real world effect of China entering the market would be a stimulated US economy, lower prices, lower inflation, greater consumer satisfaction and lower deficits. That's the opposite of what you feel.
