Capitalism is misnamed. Marx's analysis that capital has a special theoretical role in the system is wrong. Accepting the pie metaphor means falling for the capitalist framing. Capitalism is a property system, so criticize it in property theoretic terms. The problem with the system becomes clear as the capitalist legally owns 100% of the positive and negative product of the firm and employees own 0% of the product.
