There's also a difference between people who buy lottery tickets religiously, and who buy them once in a while. I like to play once in a while when the jackpots are high, just in case. Unfortunately, the answer to it is really hard, like most issues society faces today.
Yeah I occasionally will buy a ticket or two. Not often, but sometimes on a whim I get them. I figure it is probably a slightly healthier version of buying the king size kitkat or snickers in the checkout line. The cost is the same, the satisfaction is just as transient, and I'm not jamming a bunch of sugar in my face.
I've been in an online community where some users do a group buy for certain lottos when the prize is big enough. Sending $2 by paypal/venmo is easier and lower friction that going to one of the stores near me where I can but a ticket myself. I still think it's kinda dumb, but I do plenty of dumb things and I buy one infrequently enough to be ok with it.
I don't think that's the case. Most of the expected value comes from the jackpot, and even if a large jackpot means you should expect to share with 1 or 2 other winners, but the large jackpots are easily more than 3x the small ones.
If true, that's definitely a US localized thing. The places I've lived in the big winners in the big lotteries are disproportionately often middle class compared to what you'd expect if the large majority of buyers were poor.
