It does sound like you've let doom scrolling negatively impact your life.
I won't argue things are bad, but the reality is that most people are generally decent.
Sure, there's a lot of dicks out there, but they're very much the minority. They are just overrepresented in the Lemmy echo chamber (and other online platforms too of course).
Obviously it's hard to say if you're being "too picky" as it were without knowing exactly what lines you're drawing, but it sounds like you might be projecting your negative expectations onto people as opposed to people actually not living up to those expectations.
I couldn't source the 48.5 billion for personnel number. I'm seeing a total budget increase for ICE to 30 billion. But still a large number for sure. But that's total budget, not just personnel.
But look, I agree with the sentiment. I'd rather this money be spent on teachers too. I'm just not convinced that the numbers, as presented in the meme, are meaningful.
