Like other countries we have people that camp on welfare because it's easier than working.
I do agree with the substance of your post, but what do you mean by welfare? The United States doesn't really have any unconditional cash transfer programs, which is what most people think of when they hear the term "welfare." TANF for example is restricted to families with children, has a lifetime limit of 60 months of benefits for any individual and recipients must have a job within 24 months of joining the program. After doing a bunch of research on our means-tested social programs, I just don't see how it would be possible for a single, able-bodied, working-age individual to satisfy all their needs using federal transfers alone.
I also don't think it's far to call social insurance programs "welfare." They're insurance policies operated by government, with mandatory premiums garnished from wages. You have to have paid the premiums to get the benefits.
Where the US differs greatly is that our programs are abused at the top as well.
Agree 100%, though I don't think the US is alone worldwide in this regard, even if it stands out among OECD members.
