I also am having hard time getting this perspective, but not for the love of money. On the contrary, being employed usually cuts down my effectiveness compared to doing the same task out of my own volition. In other words, I hate work, but I'll gladly do the same thing for free - if someone took care of bullshit concerns like having a warm meal and a decent place to sleep for myself and my younger siblings who are still in education. I believe lots of science-minded folks think the same - they'd love to do reasearch, but maybe they want to start a family, or maybe they have parents to support, or maybe they don't feel like being someone's slave labor.
