Earlier quoted context omitted.
Both the politicians and the CEOs are only successful in direct proportion to how well the public responds to their decisions - buying their stuff, voting for their party. The public wanted cheap imported products, and so now that's what we have.
That's an overly simplistic picture. See for example recent tariffs of Chinese EVs to the US. The people buying EVs want cheaper models, but they get tarrifed just the same because the US manufacturers are complacent and far behind, yet again. People vote against their own interests all the time, all you need is a little propaganda.
But the EV tariff thing is another instance of people voting for their interests, even if the result is the opposite:
US conservatives are a) concerned about Chinese influence and b) rightly or wrongly think tariffs are the least bad form of tax, and at the same time on the left there are very numerous car union members who vote as a bloc and want to protect their jobs. So the easy answer for the politicians - in this case - is to levy tariffs.
But it's all driven by the people and the way they vote and buy.
