> so that Capitalists never actually risk or lose money
If you think capitalists never lose money then you're not on this planet. Obviously money is lost all the time. There are lots of investors, lots of companies, and few winners. This is mad. Of course bailouts happen, and they're done by the state. Capitalism would let them fail.

In this case the state is the capitalist, although it's taking the money by force rather than with a risk/reward voluntary investment. The worker isn't doing this by him/herself.
