“Selfish” is probably too imprecise a word. I think a better definition is “seemingly incapable to understand that life can be complicated and one might need, on occasions, to actually enjoy a bit more support from public resources than what he would otherwise be entitled to by strict proportional rules (which are artificially designed and enforced by elites anyway, mainly to maintain their unfairly-gained advantage through the ages)”.
Politics as a way to administer finite resources is a sad endeavour.
