Inuki, I can't +1 you, but +1000 from here.
Let's break shit down:
"We're fucked, our parents generation consisted almost entirely of morons who set up this situation we're in"
You're thinking about the baby boomers. The generation of "Our parents" was/is largely passive when it comes to leadership. Take a look at the average age in congress. (So grandparents)
"consisted almost entirely of morons who set up this situation we're in and haven't done jack shit to teach us how to deal with THEIR problem."
Because learning from misinformed people is ideal. They're aware that we have to pick up the pieces, it's not like they know how to fix it.
"told us "Everything will be OK, you can do ANYTHING and the world is entirely black and white!""
Have you spoken to anyone even moderately intelligent from our generation? It's pretty well known that's not the case.
"We'll be entirely on our own in a World that is collapsing,"
As is to be expected of EVERY GENERATION THAT TAKES OVER LEADERSHIP SINCE BEFORE THE 60'S. We'll be the first generation in 80 years to not have the previous one looking over our shoulder. Now, about second part of that: Aside from climate and resources (Both things that can and will have to be fixed) the the world humanity dwells in has been in the best shape it's ever been. Violence as a whole is down, we're socially and economically aware, and we know what needs to be done. Doesn't sound like a collapse to me.
"most young people these days have eaten up the lies fed to them"
m8, the exception (being the average Facebook/Twitter junkie) isn't the rule. I don't know anyone who "drinks the koolaid", or has even been asked to do so.
"When the inevitable happens, they'll all say "What happened? Everything was fine before..." But it wasn't, it never has been and never will be."
You make it seem like the Earth is going to outright explode. Humanity has been faced with adversity before, we'll certainly seen it again. Hell, we've been pushed to the brink of extinction. (Black Death and MAD/Cuban Missle Crisis come to mind.) As a species, we're tough, hell life in general is tough. The problems we face are miniscule compared to what we've seen.
"Again, we're all doomed, accept it..."
If you want to spend your few years imagining the worst, then do so quietly. Don't bring others down with you, because while those who care are busy improving the planet, all you're going to be is an emotional anchor. Nobody needs that.
