The dollar climb has boosted American purchasing power dramatically. That is especially important for a nation that imports as much as the US does.
Americans can buy more with their wages than they could prior to the dollar climb. That covers nearly every economy the US imports from, as the dollar has gained against essentially every currency on the planet. Simultaneously, real wage growth has been outpacing inflation for years now and is set to continue to climb at an accelerating pace due to a dramatic decrease in labor slack in the last five years.
