Can anyone recommend good sources of financial advice from the left?

My company has an employee stock purchase discount. I've worked there for a few years but never participated mainly because I don't really understand how it works. I hear many people talk about their dividends from our company stock alone, as well as other investments they make. In particular the coworker with whom I work the most has recently become a wannabe wallstreetbets newbie. He bought up some shares that crashed hard in April and has not shut the fuck up about them since then. He is a complete moron and is also regularly telling me about how he is planning to buy a house in the next few months after he pays off his massive credit card debt.

All this has got me thinking about my future. How do I balance my financial security with ideology and action towards ultimately dismantling the same systems I'm investing in?

I already know I'm a dumb lib. But is there a good place to learn about personal finance from an anti-capitalist perspective?
