" The cost of resources that a capitalist provides, such as equipment, technology, and ideas should be rewarded."

a person not capitalist.

even if risk is involved on the whole the capitalist class makes more than they lose (as long as the entire system doesn't collapse)......meaning on average the roi is always positive so risk is really 0 in the end

and the worker will lose his job if the capitalist doesnt make enough money......
the worker needs the money short term to survive. This means he is at a grater risk than the capitalist who has money saved up.
