i've always wondered why someone hasn't started a non-profit business to start selling goods and services, in which they should be able to out-compete the for-profit enterprises, since they can sell at cost just to break even, or sell at less of a markup.

you could get one going, then use what would be the "profits" (since you can't keep them) as seed funding a second similar non-profit in a different industry, then a third, by then the 2nd one could seed fund a fourth, and so on and so on until eventually, you would have expanded into every industry. and over time, since you can always out-compete the capitalist, you would have monopolized every industry with non-profit enterprises.

depending on how you structured it, you could stipulate some kind of collective social ownership, or each industry could be run as a non-profit worker cooperative with workplace democracy.

i am sure there are a thousand little reasons why this might fail, but i don't see any big gotcha? it seems like a sound idea. i guess maybe the capitalists would be willing to run at a loss to try and stop you, but that's still a good outcome? maybe try to make it illegal? i am not sure how you could make it illegal to sell good and services at break-even prices. price controls, ok fine, we will just have more money for seed funding.

i guess TLDR the ability to run a not-for-profit business seems like a pretty big weakness for capitalism.
