Absolutely. There is no business yet in which you invent money from nothing. Everyone works for someone else. It might be a capitalist boss, it might be a client, it might even be constituents or donors, but no one truly works for themselves. The only winning move is to not play, and the ones fortunate enough to not have to play were born rich. Being self-employed and/or owning your own business is just trading one boss for another.
