Welfare is the largest part of the budget, why aren’t reforms being discussed for that?

“With public debate, people would know the facts that are now being hidden… [For example,] welfare costs are now the single largest item in the budget—larger than Medicare, larger than Social Security, larger than the defense budget. We spend enough on these poverty programs to send every household beneath the poverty line in America a check for $60,000. Each family. That’s how much we’re spending… Is [welfare spending] off limits, not to be discussed? Or will welfare reform be a part of the framework [now being negotiated in secret]?”
