> We need to be able to convert labor to capital, hold it, then convert it back to gain benefits of someone else's labor later.
That part seems fine to me. The thing that feels intuitively "wrong" is that it's possible to amass money/capital way out of proportion to the amount of labor input.
The example of the "four hour work week" concept comes to mind, where the goal is explicitly to minimize the ratio of input labor to output capital. Why should 4 hours of my work now entitle me to, say, 40 (or 400, or 4000...) hours of someone else's work later?
I am also not an economist, so perhaps someone else can explain what other mechanism is working alongside your "labor is fungible with capital" that leads to this result, and whether it's a feature or a buy of the economic machine...
I'm not sure I follow what you mean. But, you can trace inductively how sellers of goods and services start to amass wealth, because prices are set by what buyers see as worthwhile rather than at a minimized "cost plus" basis.
And eventually, once you have enough capital, your new job becomes managing your capital instead of whatever you did before. There's two ways to look at that. Your labor is research and planning of your own investments. Alternatively, you are "selling" capital to others who are seeking investments, and they are "buying" it with labor. But the same story as above holds true. The price of capital (in terms of labor) becomes what the market will bear rather than a minimized "cost plus" pricing.
This duality is what it means for labor and capital to be fungible, right?
To partly answer my own question - clearly there is work we can do that is net-positive. I can spend my time turning a crank to charge a battery, and sometime later get back a subset of the energy I put in. Or, I can spend that amount of time digging up coal, or building a solar panel, and then sometime later have access to many multiples of the amount of energy that I put in.
