Socialism and associated social justice criteria vs capitalism and profit criteria.
My first job was at a company with socialist background and the same management criteria lingering on (company was privatized by workers who were majority owners after the communist system). It's just like politics on a smaller scale - you see people abuse the system all over the place and the social criteria discourages actual productivity - it's very off putting if you actually want to achieve something and eventually it spiraled down to shit and got sold off.
These days I think as much as money incentives can be perverted at least they have a scenario in which they work (measuring value as close to objective as you can get) - the alternative (determining value trough politics) is much worse.
I made the mistake of reading Ayn Rand as a teenager, and ended up being pro-capitalist, (and in American terms, conservative) for a decade. I've since become a lot more liberal and socialist.
Which of your opinion changed so radically?
