I could sit on my ass and play games all day, reek in all the unemployment benefits I possibly could, and still be nowhere near the bottom of net contribution to society.
The amount of social benefits that remain in people’s pockets after the grifters have taken their share are rounding errors compared to say bank bailouts and government subsidies (in the US).
I don’t think being a burden on others is good, but it’s nothing compared to active destruction, which can come with huge force multipliers. Every large organization have high ranked people that are rewarded for their destruction. There are entire industries dedicated to leeching off of honest people, like tax prep and time shares.
