There's equivalents in most areas, as far as I'm aware of things, actually, usually affiliated with HUD in some way or another. There's not anything I'm aware of on the federal level like WIC, though, the programs involved tend to be state or local level.
It's just that they're generally not exactly... responsive, in the sense that around where I'm at getting into gov't assisted housing is something that can involve a wait time of literally over a decade, and regularly takes years. Some places do have some form of rent assistance or subsidization, though again actually getting it involves a lot of hoop jumping and time that isn't exactly easy to afford when you're a single parent with little to no support network, assuming there's any funding available for new applicants at all (which is not a guarantee, especially in the areas of the country particularly hostile to the worse off).
For immediate needs, sometimes there's women's shelters or suchlike in an area, but they're almost always stressed to the limit in terms of capacity, so.
... we tolerate it because the people effected are too fucked up and scrabbling to survive to fight back, and too many of the folks not effected have fucking brainworms and either don't care or are actively trying to inflict that sort of misery on the less fortunate.
A very dear online friend of mine was hit by a car last summer - he thought the injuries were light and he was healing well.
Turned out there was some hidden liver damage that the hospitals missed, and by the time he realized something was wrong it was too late. He passed a few days ago.
Condolences, yeah. That's pretty close to what happened to my grandmother last year, if on a much condensed time frame in her case. Injuries took during a fall caused worse damage than the hospital noticed, and it killed her
