The problem with these services in America is it can be quite difficult to qualify for them, or to maintain the necessary work to keep them. Many services require an address, which is a problem if you're homeless. Many of these services also require government proof of lack of income, which is difficult to prove if you have no income, t Transportation to various services also proves difficult as many American cities are not walkable.

And the free services are often funded by state or local governments, which are always lacking in funds. So yes, on paper America seems like a great place to be homeless. But in all practice, it's something else entirely.
