Other than “they’re gonna stop paying you” there’s also the risk of inflation making it so you receive way less overall, since I doubt the amount gets adjusted to match inflation.
But yes, if the jackpot is so high that you’d get 2+mil per month, assuming you’re so worried about the dollar being worthless soon, you can still take the 2mil/mo and diversify. After a year you should already have plenty money to live comfortably for the rest of your life.
I don’t think it’s more crime because more tension. It’s instead a self fulfilling prophecy. Who do you think detects and records crime if not the police? Therefore more police in a area increases the number of crime data points in that area.
