If the “very ample safety net” worked, there wouldn’t be the very poor.
I am curious, what you mean by worked?
The Food Stamp and other programs are working exactly as they were designed -- to build a voter base for the Rats. The programs were designed to destroy to trap and destroy the futures of millions of poor.
If anyone thinks these programs were designed to show compassionate help for the downtrodden, then they need a serious reading of history.
