Plumbing would still be a job without capitalism. Actually, come to think about it, plumbing is just about the least capitalist job there is. Most plumbers are small businesses owned by the laborers. Plumbing products are all mass produced, but the actual plumber is valued for their skills, not because they have the capital to corner a market. Plumbers in areas where corporate conglomerates are common are usually protected by unions, too.
If you want a job that wouldn't exist without capitalism, the answer is farmer. Sure, farmers are the backbone of any society, but farmers work the land, and the land has a lot of conditions. But you can buy avocados in Michigan in January, because someone realized that they can make money shipping avocados from warmer climates year round. It's terrible for the land, terrible for the environment, and terrible for local farmers who cannot compete in the race to the bottom, but the capitalist cares not for these things. Only profit nourishes the soul of the corporation.
I can understand the appeal of a piece of bread that's been soaked or buttered or even just toasted and salted. I bet that's delicious, if done right.
My question is, why the other two slices of bread? What's the thinking there? Why not have three slices of delicious middle bread? If the bread is good enough on its own, why not eat it alone?
It's like if you made a drink of tepid water by adding ice cubes to a glass of warmed water and then letting them completely melt until room temperature. Who is this recipe for? "Oh, but maybe the ice cubes are flavored" OK then why freeze them before melting them? "Maybe the hot water is flavored with herbs that rele-" Bitch, that's tea.
I'm so confused, I'm getting mad at imaginary arguments I'm having with hypothetical morons about analogous situations that only exist in my head.
