"People" you are referring to want a level playing field. If the Chinese government is tilting the field, there aren't a lot of good options. You can either watch the Chinese subsidize draining most productive capacity from the rest of the world, erect trade barriers (my preference, but it would require cooperation with other countries, which... ain't gonna happen for a while now), or try to tilt back.
Are you unfamiliar with the concept of cornering a market? Sure, uber was offering lower prices subsidized by VCs until taxis were driven off. After the fact they raised prices back up. Or what Amazon did with diapers.com? It is not wise to let your geopolitical foe gut the productive capability of your economy. It’s how America took over dominance from the UK by taking over the high tech business of the day back then (textiles).
It’s fine for the consumer in the short term but a flawed long term strategy.
Yeah sure but then you do it properly. Why did Trump have to coerce them into the deal (by threatening to fire the CEO)? Just imagine what's going on behind closed doors.
If you truly think Chinese subsidies are artificially depressing prices, then just buy Chinese goods to take Chinese’s people’s hard earned money.
