If someone has to work to make money they are not rich. It doesn't matter what they do to work or how much they get paid. They are still selling their time and labour to someone else. They are being exploited by their employer even if they are "self-employed".
People who work are not the problem with the world.
The people who are a problem are the people who do not work but still make money from unearned rentier incomes. Landlords, patent holders, shareholders and more. People who earn money while sound asleep in their beds. People who make money without lifting a finger. People who make money by breathing in and out.
These people used to be aristocrats. Now they are oligarchs and plutocrats. They are presidents too.
The French had a good idea about what to do with these people in 1789. The Russians took up the idea in 1917. The Spanish tried too and so have others around the world too.
Right now it is more important than ever to kick out the jamms (motherfuckers) and all around the world too. The future of humanity depends on it.
