We will pay those taxes when in effect. It will make those same products made here look less expensive. By buying local, we encourage job creation here over job creation in China. More people with jobs can buy more things, either from the US or China. As more people realize they are no longer undercut by cheap foreign goods from enemy governments, more businesses open up because people realize their ideas and efforts will pay off, rather than be stolen by China. Fewer people are left unemployed and more monies flow through the system, being taxed at each point of exchange, paying down public debts but enriching each along the way. Productivity will start to go up as people make investments to curb local cost inflation, but now other jobs actually are available, allowing a much easier migration to these other jobs than were otherwise appearing in China to enrich China's locals (after all, our unemployed don't get offered jobs in China to fill their manufacturing needs). The economy continues to grow and more people feel happy and comfortable that the future won't be taken from them. We go through another 1980s-type decade or longer and we relearn bedrock American principles, changing a generation of liberals into the Alex P. Keatons of Trump's time as president.
