Same thing is true for taxes and regulations. They all have a cost that affects the bottom line and which must be managed. Question is, is it worth paying that cost in each case? Reasonable people can disagree on that; not everyone on the other side is a petulant child.
Businesses can complain against tariffs, taxes, & regulations. That, by itself, is beside the point. What is important is how companies manage regulations and tariffs. You can complain if you want, but what matters is what you do.
If a business's entire manufacturing capabilities are overseas, and they have no US options, then maybe all they can do is complain.
My experience us with companies that built themselves up by manufacturing in the US. They are not pure importers. They have become true global companies with manufacturing everywhere, but trending towards moving manufacturing out of the US to countries like China, because of pressures from Wall Street. Those companies have been gradually shutting down YS manufacturing. Tariffs change the landscape for them, and they immediately keep jobs in the US...which helps many people living paycheck to paycheck. Tariffs immediately help those people by keeping them employed.
Regarding those people who live paycheck to paycheck, especially in California, there are many ways to reduce regulations and reduce taxes, but the government there has decided it is worth the cost for such people to pay those costs. Tariffs, in isolation, won't be the primary cause of their financial pain. Trump's opposition there play a key role in that cost of living. Their objection to Trump doing what they do is not principled; it is political.
