I agree. The idea that time is not risked as an investment is, IMHO, deeply weak minded. Dollars, when used to purchase labor, are essentially acting as concentrated time. It's like a conversion from matter to energy and back. Walking around with lots of dollars is like holding lots of time, more time than you actually have life. So someone with a lot of money has, in effect, a vault of highly dense time they can chip off and trade with someone else, buying, essentially, more life than they could ever have (i.e., paying others to do things they could never in their lives have the time to do).

We humans are such primates, though, that we regard those with far more money as essentially higher class in the social hierarchy, and venerate their actions, and their property, as inherently more valuable than someone with less.

So when investing in a company with money, you are able to participate in that company by buying someone else's time. But, assuming a fair exchange (which is usually not the case for the laborer), then the one who works is trading one year of time for one year of time from the investor, in the form of dollars (assuming a 100k/year salary). However, the investor isn't trading their time in the form of calendar time, but in dollars. The worker is trading their time not in dollars, but in calendar time. The point is, it's an equal exchange. Which, if there are two people, then both would split the reward 50/50 assuming all else is equal.

We get confused as primates because we are comparing dollars and time, not realizing that we need to convert to common units. To know the true fair split, we have to know how much each person invested in the same units, time or dollars, but not both. We have to convert all dollars invested to time, or all time invested to dollars, in order to know the true investment ratios. In the example of Person A and B, both put in 1 year of time, hence a 50/50 split.
