Devaluing the dollar is an import tariff on all imports. Not ideal but since Trump endlessly complains about China's currency trade advantage he must think this is brilliant.
I don't remember Trump recommended we buy up valuable natural resources last year like China has been doing to beat competitors, instead Trump was supporting the wasteful stimulus and now he is upset his taxes might go up.(Where did he think the stimulus was coming from?)
Trump believes in demand side economy. This is what most of the left believes in
right wingers believe in supply side economy. You can not consume unless you produce. Demand is unlimited. Its production that limits the demand. Consumption is the effect of a good economy, not the cause of it. Its production that improves the economy.
