Have you read history? When you say that 500.000 years passed and you feel those generations cared about the world, but boomers just dont, it sounds like you havent.
You make it sound like everything was just amazing and peaceful and selfless and then boomers just destroyed all of that... :) Read about history and how people treated eachother. America was created in 1776, founded on genocide of the native people. Everyone cared about eachother back then, looking out for eachother?
You can read about hundreds of these historic events around the world. Humanity has a history of taking things from eachother and being cruel. The way your generation looks at boomers as the problem is a bit strange. Its like you just woke up, and you look 20 years back and think you have identified boomers as the problem and now humanity is going to die because of them. Its a bit funny and you would see that yourself if you had my perspective.
