Remember generation X? They were all a bunch of pot smoking, grunge music listening, flannel wearing, slackety slackers. And then they reinvented the internet, made a new sector of the economy, and had families.
Remember the baby boomers? They were all a bunch of pot smoking, stoner music listening, tie-dye wearing, hippies. Then they marched for civil rights, made the modern feminist movement, fought the cold war, and had families.
Remember the greatest generation? They were all a bunch of rum running, loose moraled, dance shoe wearing, flappers. Then they survived the great depression, fought Hitler, and had families.
People grow old, remember being lazy 20-somethings, and project their envy and regret onto their children.
