maybe the reason why so many want to start they own business is because u can get fired for no reason. being it's own boss gives you at least the freedom to not always live in fear of being fired if you do something that the company does not want, like getting pregnant, i have read enough stores of companies firing pregnant women and i cannot believe it's legal to happen.
in europe at least that part is gone, you start your own company not out of necessity but out of motivation.
