By the way, I suppose an issue where I'd criticize the left for not being "left enough" would be drug legalization. That's obviously going to be a problem as long as our entire political system is financed by the War on Drugs*, but it's quickly becoming what could be a political winner for the left to appeal to libertarians and BLM/criminal justice reform supporters on that issue.
*This is, predictably, one of the issues where the base is clearly there, but the politicians are not.
Do you just mean the prison guard lobby, or something more than that?
That
and several other industries, all which obviously have their own connections.
(Obviously I'm being slightly hyperbolic when I say the "entire" political system.)
