Why? Only a total buffoon would ask such question! Lets see:
1- The United States had more mass shootings -- and more people killed or injured in 2017 and 2018 alone -- than all Europeans nations combined over the last 20 Years! Such as the Florida shooting that Killed more Americans than Columbine which used to be a measure of how bad things are in USA.
2- 50-Million+ Americans with NO health care since USA does not have even the most basic of social services which is Government run Universal Socialized Healthcare, whereas all Europeans have healthcare since like all other developed Nations they have Universal Socialized Healthcare
So only a total Trump Republican IDIOT would not know these facts or deal with them.
Lets see, since the election of Donald Trump, Wall Street been hitting Record HIGH after Record HIGH, while US Dollar been hitting Record LOW after Record LOW vs Euro.
With the US Dollar hitting a 3 Year Low of 1.25 to Euro Today Jan/25/18.
So does that answer your question? This means People World Wide, including those who can afford it in USA, would rather be in Europe and hence hold Euros than be in USA. Hence Euro "Bitch Slapping" US Dollar and Trump lower and lower vs Euro.
So People World Wide, with their Wallet, are saying that Europe with its Social and Welfare services and strict Gun controls and strict controls on Big corporations, is a FAR BETTER place than USA, a country lead by Wall Street for Wall Street, leading to Obama Trump being tools of Wall Street and Military Industrial Complex and the HELL with American People on Main Street.
Does that answer your Stupid Question?
