I just don't agree with this viewpoint at all. There are plenty of profitable startups directly focused on education and the environment. Maybe you don't agree with their definition of meaningful but don't let perfect be the mortal enemy of better.

whatever meaningful means to you should be a highly personal measure, not the classic, obvious societal ones. It also helps if the macro-benefit of the act is a symptom of the behaviour vs. the goal. example: I ride a bike to work everyday because it's fun, good for me and cheaper than driving. I dn'to it primarily because it's good for the planet, but hey, it's a nice bonus. We need to look for lots of opportunities that do good for others as a consequence of doing well for ourselves, not a subsistute.
