Everything is relative. I think its hard to generalize. There are lots of startups that are much more lenient with remote work, and many that embrace the basecamp-style company values. In general, if you are not in SV or maybe NYC, big open source job markets, you tend to hit a pay wall pretty quickly.

It is much harder for me to find a startup that pays as well as a more traditional IT shop would pay me. I can find a 130-140k job in .NET here in South Florida with relative ease. For open source, there are maybe a handful of companies willing to pay that kind of money. In general, these enterprise places will offer very good benefits (vacation/401k w contribution/paid healthcare) and the work is not hard in comparison.

At startups, its just spottier. Last place I worked paid me same as before but didn't contribute towards my healthcare.. That was an extra $1300 / month that had to come out of my paycheck and an expensive lesson.
