I found your post to be a bit unproductive (despite legitimate content) because it was so deeply ridden with spite and disdain; too much focus on name-calling! Without the smug superiority complex and palpable hatred for a certain group of people you clearly consider beneath you, it would've been a bit easier to engage with.
Even a bit of humility about whether your personal vantage point and opinions are accurate pictures of the entire "real world" would help...
Basically, each of the 5 points I listed comes down to, "Momma said there'd be days like this, days like this Momma said!"
I guess, at this point, I'd be curious about what, in particular you found "heinous", "poisonous", "horrid", or likely to lead to one becoming a "burnt out husk of a human being" before the remarkably specific age of 40. However, I suspect that you'll find you've imported a bit of your own baggage into your explication.
