Inflation is caused by a number of interacting factors, money supply being only one of them. Your understanding of it is at least as solid as Trump's. Anyway, he does want to raise taxes on poor people who shop at Walmart, by imposing high tariffs on goods imported from China. Then raise the price of food by deporting the low-paid migrant workers who harvest and pack most of it. Of course, both of those measures will increase inflation, but closing the schools will put a whole new generation of cheap labour on the market. Eliminating Medicare will cover the huge tax breaks for his rich donors. Musk won't have to peddle his sperm to make ends meet.
