This is really it, "nothing matter." We've had it so good for so long that some people think that they're untouchable, that there are no consequences for poor decisions and doing things "for the lols." How does that part of the saying go, "good times create weak men, weak men create hard times?"
Even to look back and paraphrase posts in the Murica thread, "you're whining," "you're overreacting," "none of this affects us," "laugh at the libtards," etc. Elon Musk is the perfect example of the product of it, everything's just a meme and nothing is to be taken seriously. And it's all because nothing matters.
