It's not actually rigged though. People just sell themselves short due to information asymmetries and a just plain crappy business model (work for hire). Customers see it as a risk so are reluctant to pay much, but it's your skillset so from your perspective there's actually little risk. Better to license technology but maintain ownership so you can sell it again to others. And now that the risk is gone, the hotter the technology the more you can ask for working technology you can demonstrate. Of course this isn't possible in all technology niches but I'd say your goal when self-employed should be to maneuver into areas where it is possible. Business is a game of avoiding being the commodity that others profit from by building into wealth. Work for hire is a commodity.
