As many as it takes I guess.
So why has voluntary charity proven inadequate?
For one thing, more people jumped on the charity bandwagon because they can't turn down freebies. I know two people right now who each have 3 free cell phones the government is giving away. They applied with different companies and, since the government doesn't take steps to prevent fraud with it's programs, they were approved and got the phones. One told me 250 minutes was too stingy, so he got three phones with three different numbers and a total of 750 minutes a month. I just love it when beggars get choosy and demanding.
The scammers overload the system. I think this is true with private charities as well.
Also, I think more people might be willing to donate if they weren't already taxed to the max for government programs. Even with taxes, studies show that Republicans give more to charity than Democrats. Perhaps private charities would suffice if the Dems would chip in and those who don't really need freebies would opt out.
I am all for a safety net because some people are simply unable to fend for themselves. I have big issues with the able bodied who think work is for suckers. Problem is that some started seeing the safety net and as a comfortable hammock and they don't want to get out.
