Switch the Dollar for the Euro?

Question

Everyone complains about how the dollar is down, and is worth half as much as a euro. And considering all or mostly all of european countries have switched to the euro, why doesn't america? I'm definitely not an expert on economics or the money exchange, but it seems like a fairly simple alternative.

Answer 1

It's a little known fact, but the euro is not actually a currency.  It's a way of life similar to Taoism or Platonism.

Answer 2

It would not benefit the US to give up its sovereignty the way many nations in EU have. Bad idea. and totally impractical.
