There’s no risk to the capital class. They do not risk their livelihoods, they barely risk their next yacht. The only people that share risk are the working class, not the owners.
the risk is primarily shifted towards the beginning of the businesses lifetime, later it can only really be hampered by skill issues and aggressive competition forcing you out of business. Think boeing. Or any number of companies that just, no longer exist.
Once you get to a certain size, it's really hard to fail unless the world literally changes, or the government kills you or something silly like that.
I would generally disagree with the statement that the working class is the one sharing the risk. Unless you mean some weird tangential thing, like being let go because the company fails, but that should be an obvious risk, i would think. There are a few exceptions, nortel being the only real prominent one i can think of. And that's mostly because they all got fucked over, not because it was risky, so that shouldn't have even happened.
