Yes, as a leftist, I’m not a believer in that. I’m of the opinion that the supposed risk that investors take is overstated. The average investor is quite wealthy compared to most workers, and can afford to loose a bunch of that money without it causing significant harm, even leaving the investor still significantly wealthier then the worker. On top of that, many investors have insurance, or a wide portfolio of low risk stocks, guaranteeing them continued exploitation without risking much.

Compare this to a worker, most of whom can’t afford to go without paychecks for a single month. Meaning that the loss of a job is far riskier then the investor’s supposed risk of loosing their investment.

This transaction between an investor and a worker (if you look at it as a transaction) is always biased significantly towards the investor, they will grab proportionally more of the profit and tank less of the loss. So I would say the average worker is both risking a lot more and reaping less of the benefits.
