According to the charts in the cite, states [which create the rules for welfare & food stamps] have long since enacted such regulations as work, education, or volunteering, as a prerequisite.
My only personal experience is unemployment, when I used to get laid off every year, for about 6 weeks, and I know how bad that was. First, there's a 'waiting week': no income. [Tough to take when you're just scraping by] Then, you have to be actively looking for a job, recording dates, times, places, people contacted in an effort to find work [I didn't want another job!!!] and if the state finds anything falsified, you're disqualified. They loved finding reasons to disqualify people, and I can only imagine how much worse it is for collecting food stamps and welfare benefits. Maybe it's just 'SOP' to people who have never known anything else, but for those who are used to earning a living [even if just barely] it is a humiliating and depressing experience, and trying to stretch the little bit of benefits to cover what you had twice as much to pay for before is a never ending headache. The notion that people who were used to working for a living would consider it acceptable, much less preferable, to working is just inconceivable to me.
What the Republicans are doing is kicking people who are already down, because it's easier than tackling the real problems - which is actually their job.
