This isn’t true. Homelessness is a problem. But America has many social services available. Sadly, our current president is trying to reduce or eliminate many… He has had very limited success doing so.
We have 770,000 homeless people (average on any given day) in a country of 340 million. Most people that experience homelessness - the duration is a year or less.
We want to get that number to zero, but it’s just plain false to claim that families in the USA end up on the street so easily.
