The problem is that the individual is not being greedy enough for their own control. They are being greedy for many wrong things, not exclusively but many.
This problem is solved with education not control, which is what stallman had tried to do. People should understand what they should be greedy for i.e. protect at all costs
This might be stretching the definition of greed as it's commonly understood.
Edit: for clarity I not implying negative connotations to either side. I think corporations are doing exactly what they should do. But I also think people need to be more responsible for their choices and the consequences thereof.
Living by greed in the market economy is an exercise of exploiting a positive feedback loop. Larger entities benefit more from it, and the larger they are, they more they benefit.
The problem is that there are political entities that can be manipulated to give unfair advantage and or effective monopoly control by making that cost of entry so prohibitively high.
Education will ensure people will understand that political entities are no more inclined to have your best interest at heart than a corporation, there both made up people it would be moronic to think they'd act any differently.
Educational policy is not exclusively for the benefit of the recipient either intentionally when pandering to teacher unions or unintentionally when said policies set targets that drive the system in the wrong direction per Goodhart's law.
