Import tariffs and low interest rates have helped the economy immensely, also.
Yes, but artificially low interest rates are a pernicious poison that eventually will do an economy in. And as for tariffs, most new brooms sweep pretty clean, but in the long run, they're killers. I don't mind them being used as leverage to get better trade deals (although the best trade deal is perfectly free trade) but as "protection" they only protect producers and consumers from low prices.
