Companies pay what people will accept and what they can offer for a job. It has nothing to do with welfare. In fact if there was no welfare do you think people would demand more or less to work? My guess is much less.
It's not abuse. Your imposing your standards on other people without their concent. People should be able to make whatever arrangements they find mutually beneficial. Uninvolved third parties shouldn't have a veto power over how people work.
