Eh, i wouldn't assume that.
My cousin worked for LinkedIn for a year and he had a HIGHHHH salary and bonuses/incentives/stock options, but a year ago he left for a better job with Sales Force.
I honestly didnt think it would get any better for him, especially because he worked at Google before LinkedIn.
But it just goes to show you, no matter how good you think you have it, theres always better opportunities out there if you arent complacent.
Who knows, his boys brother may be better off with the new company...maybe not.
