Why would a good capitalist pay years of salary, percentages of the company, or whatever else you're talking about offering, when they can simply outsource the automation job for $5,000 to China? And then fire you.

And then hire you back on a $5,000 1099 contract to automate other people's jobs?

You seem to be trying to come up with some sort of "fair" system, as if that were how compensation works now or ever will work.
