The criticism should be directed to the freeloaders, the 12% of the population living off the public dime who are otherwise able bodied but choose not to work. These folks shouldn't be allowed to vote, let alone collect an average of $30,000/year in benefits.
These are the folks using all of those services, roads, schools, etc. while not contributing one penny in taxes and not having a vested interest in society.
Obama won't criticize the 12%er's because he'd lose their vote.
