>Being granted equity in lieu of salary is asking me to invest in the company.

That is exactly right and I think what people are missing here. I mean even legally if you look at options purchases, you are literally investing. Even with stock grants, unless the company defers the strike tax through a loan mechanism, you will pay taxes as though it were real income.

> In fact, since I'm limited to investing in only their company (instead of being free to invest it in whatever I want), it is a large burden.

There's two ways to look at this. Yes, you're locked into investing in just the company, but you're also being given the chance to invest in something that's not available to the general public. These investments are risky, but often very good.

I'm currently coming to the end of my 4-year vest in a company that was acquired 9 months after I started. I gave back some salary in exchange for more options when I started since the company looked very likely to exit. That investment, over the past 4 years, has quadrupled. Even in a bull market, there aren't many stocks that have ~40% annual returns over that time. And that's not even accounting for the fact that these kinds of investments are better from a tax standpoint (flexibility to avoid AMT, long-term cap gains, etc).

As others have said, it's not a simple decision. You're being given an investment opportunity that is normally only available to VCs. But unlike VCs, you can't diversify across a portfolio. But, also unlike VCs, you can directly influence the success of the company...I learned after our acquisition that in the few short months I was there, some of my actions played a significant part in us getting acquired. It's a really unique investment opportunity that's available to very few people. It doesn't make stock options as a class of investment good or bad bets, the exact details of every situation determine that, which makes it very hard to make blanket statements like many people are doing here.
