This is a counter to the Democratic party supporters you see everywhere who always get irrationally upset at third party voters, not about Republicans.
Plenty of us Democrats are very much in support of a ranked choice voting schemes, or similar structural rules like non-partisan blanket primaries (aka jungle primaries). The most solidly Democratic state, California, has implemented top-2 primaries that give independents and third parties a solid shot for anyone who can get close to a plurality of votes as the top choice.
Alaska’s top four primary, with RCV deciding between those four on election day, is probably the best system we can realistically achieve in a relatively short amount of time.
Plenty of states have ballot initiatives that bypass elected officials, so people should be putting energy into those campaigns.
But by the time it comes down to a plurality-take-all election between a Republican who won the primary, a Democrat who won the primary, and various third party or independents who have no chance of winning, the responsible thing to make your views represented is to vote for the person who represents the best option among people who can win.
Partisan affiliation is open. If a person really wants to run on their own platform, they can go and try to win a primary for a major party, and change it from within.
TL;DR: I’ll fight for structural changes to make it easier for third parties and independents to win. But under the current rules, voting for a spoiler is throwing the election and owning the results.
This framework you describe is still grounded in a large number of producers intentionally avoiding undercutting the competition in price.
If a profit can be made selling burgers for $10, and literally every burger seller knows that I’m happy paying $15 for a burger, they still have to compete with each other to get my business. Am I going to choose the place that charges everyone $10, or the place that I know engages in opaque pricing and is offering me $15? The most sophisticated price discrimination algorithm in the world doesnt do any good if the other burger shops don’t play along.
And this plays out every day in places like airports. Yes, I know I just need to eat before I jump on my connecting flight, and I’m not super price sensitive in that situation. But I won’t go to the place that’s far and away more expensive than another, or who I just recently read about on some travel blog as a price gouger.
And for a more concrete example of something that happens today, with services that are worth a completely different price than what it costs to provide it, and where everyone knows the buyer is valuing the service at that high value. Say I have an unfinished basement, and I want to hire a contractor to finish it with drywall, paint, flooring, HVAC, etc. It’s obvious to everyone how much that project adds to the livable square footage, and plenty of public valuation models show exactly how much that job adds to the value of the home. And everyone knows I’m about to list the home afterward for sale. But if 10 contractors are competing for the job, they don’t really care what value it provides to me if I choose not to hire them, so they’re bidding prices that cover the level of profit they want to make on the job, while not ceding the price advantage to the competition. The presence of competition tempers the price gouging.
So I still think competition is the key policy to pursue. Competition solves the problem being described here, and any market with this kind of individualized price gouging is suffering from insufficient competition.
