> money to help the poorest people comes from the rich ones

It comes largely from the middle and working classes, who pay a higher tax rate than wealthy people.

> many poor people can make a country hard to live for the richest (crimes for example)

I'm not convinced that poverty causes crime. It might be lack of public services, such as health care, shelter, food, education (creating social mobility), safety net, etc.
