Use the right tool for the job, I say.
I made a decent chunk of change with capitalism. I have a modest house and am well positioned for a middle-class retirement.
Now I work for the government in a field for which I find the capitalist options wanting.
I give away my programming guides for free online with no ads, but sell paper copies of the books for profit.
Could I make more money by charging for the online versions? Sure. But some things are worth more than money.
The quest for money doesn't ruin everything, but it sure ruins a lot of things.
Bell Labs of yore would be my dream company to work for.
