There is not "widespread poverty in European countries". "Widespread poverty" is what they have in Africa. In Europe the poor are kept fed, housed and clothed precisely because the admittedly very large and inefficient in many ways governments spend some of the tax money they bring in to keep them that way.

This causes problems, to be sure, in that it disincentivises some, but not all wellfare recipients from trying to escape their poverty, but it prevents people from dying of hunger in the streets, which is, imho, a good thing.
