Your standard of living doesn't track your currency valuation. Your whole economic premise is more flawed than a liberal trying to explain church to an athiest.
For instance, the Dollar has been declining in value since 1930. If our standard of living tracked the decline of the Dollar, then we'd have fewer air conditioners, fewer cars, fewer TV's, fewer telephones, and less food than Americans had in soup lines during the Great Depression when our Dollar was at or near its peak high.
Clearly that's not the case. So a further decline in the foreign purchasing power of the Dollar is not to be feared, but rather, embraced.
The more that the Dollar falls, the more expensive foreign imports become...so Americans buy less of those foreign imports and more of American goods.
...And selling more American goods won't lower our standard of living (but you did give me a good chuckle at that claim).
And you think I am funny, you're a riot.
Our standard of living bit the dust in the 30s, and has been flat or in decline since Nixon's second term. We did get a big boost after ww2, and "hello" the dollar was super strong after ww2.
our problem is that the nation doesn't produce the wealth it once did. Free Traders have killed the money machine that the USA once was, sent it all over to China, India, Japan and Mexico. Less wealth, less wealth to go aound equals devalued currency.
