"Spend less time thinking about getting sex" hahahahaha yeah okay.
Look, maybe when you're in your 30s or 40s and you've got the wife and the kids and the minivan and the bills and the mortgage you can focus on the more noble things in life, like making the world a better place so that your progeny will have an easier time of it.
But, in the meantime, for those of us without children, fucking is a pressing issue.
EDIT:
I'll be still more blunt--the people who gain the most from us "making the world a better place" are those with kids and a stake in society. You are trying to take advantage of us.
You should've gotten us healthcare, but you fucked it up. You should've gotten us a safety net, but you fucked it up. You should've gotten us cheaper student loans, but you fucked it up. You should've gotten us more affordable housing, but you fucked it up.
So, no, I'm not going to help you beat cancer so you can spend an extra year with your kids (who are going to be bankrupt the rest of their lives because of your medical bills).
EDIT2:
You couldn't even manage to kick out the bastards in office who are running the alphabet-soup agencies that are ruining our country. There. There's your fucking legacy.
