This is an absolutely silly mentality:

1) A lot of people do make money off of employee stock, you just have to be reasonably intelligent about it. This blog post is a good way to model risk/reward.

2) Thinking of your employer as your enemy is a great way to set yourself up for failure.

3) Don't think of stock as worthless, think of it as a bunch of lottery tickets. It has some probability of being worth something based on the lottery.
