I know the idea of change is scary. The world is an ever changing place and part of being human is adjusting to those changes. Just because we had to push rocks up hill 60 hours a week doesn't mean we shouldn't strive towards a society that can do the same work in 35 hours.
There's no reason our great grandchildren need to attend our parents school system. The Greatest generation came back from the war, had lots of babies and collectively invested in this countries infrastructure. The improvements they made placed our country among the best in the world to live.
We can continue that society by simply building less bombs.
