Many investors will do whatever they can to stop you. I've personally interacted with a few of them, who've instructed me that if I took their money, I should not "take anything more out of the company than what's required to eat, sleep, drink". Of course, their ultimate ability to enforce that may be questionable, but the guys 'round these parts are certainly not shy about their expectation that founders live on practically nothing.
There are good investors and there are bad investors.
Good investors won't take board control after a seed financing and will understand if someone with a family takes a $100k+ salary.
Now, if you're a 20-something who can survive on ramen, a mattress on the floor, and internet, investors will be very suspicious of you taking a $150k salary.
