Things are pretty good right now. They could definitely be better, there's no doubt about that, but we're far from 'doomed'. Trump is massively cutting back regulations, which is great for us Libertarians; but he hasn't gone nearly far enough in my opinion, there are still far too many laws on the books. Over-regulation is how you get monopolies.
1. The stock market doesn't mean shit to me so I'll pass this one
Well it should. You should be investing your money. Plus, a good stock market is good for everyone; it's basically a snapshot of how the economy is doing, and everyone benefits from a strong economy, I don't think anyone would argue with that.
2. Average lifespan has actually dropped, and has continued to drop.
Mainly due to the opioid crisis and suicide rates of white men & transgenders. If you're not depressed or haven't gone through SRS you're pretty much golden.
3. Yeah medicine has advanced, but access to that medicine is getting tougher. Insulin is still expensive as fuck for no reason.
There are countless options available to people who can't afford their medical expenses.
Of course automation, climate change and ocean acidification are both big issues moving forward.
These issues are not as big as you think they are. People having been freaking out about climate change forever; and guess what, we're still here. The solution is to stop worrying about carbon emissions and building more nuclear power plants; and solar power as well, but only deployed in a way that makes sense, as opposed to, I don't know, putting solar panels under the road or whatever.
So all in all, for the most part, I'm really not worried. Also I couldn't get a fuck less about automation; and this is coming from a guy who's job could be replaced by a trained monkey.
Our biggest problems I think are cultural ones. One's that tell women they don't need men, the nuclear family is obsolete, and you can change your gender. That you don't have to do shit and the government will take care of you. Welfare programs are financial disincentives towards a strong family unit; it's why the black community is failing. Obviously blacks are the most affected by this but you see it in white families too.
