Well lets see meditation praxis in one form or another has been around for at least a few thousand years. And it hasn't caught on, so probably not. The scientific evidence where people got brain scanned shows that it definitely has beneficial effects, but it takes about 10 years of 2h+/day to get proficient enough to really make a difference. I would say changing your environment to fix root causes of your suffering is more cost effective than trying to change your brain.
If you get rid of capitalism and the inherent wealth inequality, you probably won't need meditation any-more.
