"Having luckily never needed public assistance"
You should probably do some studying up. You never know what cruel blow is in your future. Most of the seniors I work with never expected to find themselves in that position either.
Section 8 housing from HUD is probably the best deal in town. Thirty present of one's income, which is usually just a Social Security check for most, is minimally adequate but it does allow seniors to maintain some measure of dignity in their final years. However, it's rarely enough to make it through the whole month even with the stipend they get in food stamps (which has been drastically cut). Also, most states have something called the Medicare Savings Program where state Medicaid pays the monthly Medicare premium instead of it being deducted from a senior's Social Security check. That's a very big saving for a senior but it's also another benefit that Trump wants to eliminate.
I haven't read all of Carson's proposed legislation but there's not a doubt in my mind that Carson is following his marching orders from Trump to starve the beast (HUD) out of existence. In fact, Carson probably drafted this legislation as a show of good faith to Trump in hopes it will save his job. It probably isn't going anywhere, especially in a mid-term year. But it does show where Carson's mind is.
Unfortunately, the elderly and most vulnerable are now left to deal with the most scurrilous scum in America's political histrory. Carson makes the top 10 list.
