Socialism doesn't work, because people are lazy and abusing the system.
Capitalism doesn't work, because people are lazy and abusing the system.
You understand that lazyness has nothing to do with both systems?
Communism didn't fail because people were lazy, it failed because it became a dictatorship. Capitalism isn't failing because people are lazy, it is failing because in his very basic idea it will always lead to an increase of inequality. And when growth is no longer there to compensate those inequalities, it becomes pure theft.
Lazyness is a simplistic stupid myth of the typical old right winger trying to claim that young people and hippies are lazy assholes...
