Eh, stock comp is real comp. They can't sell it at the moment, but if the $2T IPO is anywhere near a success, they'll make absolute bank.
More companies, especially startups, should do stock based comp. It gives the employees a vested interest in the conpany and a share in the success. When the owners cash out, the employees get at least a small windfall too. Normally, the employees just get a worse work environment.
