Exactly, thats the best way to see it and makes the "Give back our stock" more ridiculous: employees get les money in cash because they decided to invest some part of their salaries in the company shares, so, if the company go to IPO and they get rich they are not geting rich because of how much value they provide to the company, they get rich because they could recognize a great company in the early days and invest on it.
Is like saying to an angel you didn´t help me so much in your mentoring so give me your shares back.
