Being slightly economically less well off (although still doing exceedingly well and having lots of opportunity) is not the same thing as “boomers wrecked the world”. There are people in very tough situations and as a society we need to help them more but the vast majority of young people (and I say this as one who isn’t doing exceedingly well) need to grow up, cheer up, and start taking more responsibility for things. My parents may have been able to buy a house, but there is much much more about their younger lives that I am glad I don’t have to deal with.

Younger people will be the ones enduring a transformation of our economy as they attempt to prevent the worst consequences of global warming.

Also, not sure what "grow up" means in this context. Quietly endure injustices and environmental catastrophe instead of speaking out and taking action?
