"Many jobs seem to have a net negative value for society - soda, highly processed food, credit cards, car dealerships, (most) sales people, etc." Rubbish. Soda taste great, I love it. Don't tell me what is 'good or bad for me' - I can figure that out. 'Processed Foods' feed the world. They're not fundamentally unhealthy, can can absolutely be part of a decent diet. Credit Cards - are an amazing financial innovation. Consumer credit is a really big deal that helps grease the wheels. Wherever there is no good consumer credit system - the economy is crap. Car Dealerships and Salespeople - they definitely serve a function and it's why they are among the highest paid. Most people still like to test cars. The car industry relies on the model of dealerships and Tesla riding without is just like a new airline entrant just running only the profitable routes, and not carrying the longer tail ones. Also society has changed a little bit so admittedly the model could adapt. All of those thinks you mentioned could be improved, and can be risky, but without them we'd be much worse off.
