Are Americans really the waste trash out of europeans?

I Heard a saying that goes like "Americans are the waste trash out of europeans. Only dumb ignorant or violent who don't know how to live in society ones left Europe and immigrated to America. Why people who had good life in Europe would leave their homelands? That's why there is so many violence and serial killers and crime in the US".

Is that true?
