The economics term for this is price discrimination. Nothing to do with racial discrimination, it’s discriminating based on willingness to pay.
But usually it’s not done by raising the prices above normal it’s done by setting the regular prices higher and then offering a discount to people who aren’t willing to pay less. People tend not to get upset when it’s done that way. Student discount at the movie theater is a form of price discrimination. People accept it because they’re being nice to people that don’t have a lot of money. Seniors discount? Also being nice, I guess. But the reality is they know everyone else is willing to pay more so they charge more.
And this has already been happening online. About a decade ago I noticed what when I searched for flights from an airline then went to facebook, I’d get an ad from that airline offering a discount. Not as sophisticated as attempting to determining the exact price I was willing to pay, but it’s along the same lines.
But the problems with these schemes is that people quickly figure out the system. I just made it a habit to search for a flight, then go onto facebook to look for the discount even when I’d be willing to pay even if there was no discount. But why not trick the system into thinking I didn’t really care about booking the flight and get that discount?
I feel like they kinda have to stick with Vance on the ticket at this point. Past the deadline, ballots are already being printed and such.
Though maybe that’s just for the top of the ticket, I don’t know.
Also it would require Trump to admit he made a mistake, so it seems unlikely he’ll be off the ticket.
