> Anyone can run in primaries and they don't even have to win.

Nope. You need to meet requirements which vary by state. Most require some mix of signatures (often thousands) and fees (can range from hundreds to tens of thousands). The high barrier to entry is another long acknowledged problem (example: https://www.cnn.com/2012/01/22/politics/newcomers-campaign-c...) which has only gotten worse. If you want to stand a chance to win (and you'd be a fool to spend the time and money to enter if you didn't) expect to spend many millions. (see https://mcfn.org/node/7427/2020-us-house-races-cost-868-mill...). Go ahead and count the number of people in congress who were living paycheck to paycheck before running for office. Most of them are not millionaires by chance.

It's also worth mentioning that primaries are not required to be fair, as we saw when the DNC colluded with Hillary's campaign to undermine her opponent and install their preferred candidate ahead of the 2016 primary election.

> Ranked choice or any other voting system is not going to change this dynamic

experts disagree with you, and for good reason. There's zero incentive to not vote for the candidate you want in office when your vote will go to your next choice if your preferred choice cannot win. The problem we have now is that we're forced to vote for who is most likely to win no matter how we feel about them. There is research showing it would increase voter turnout and it would also open the door for more than just two parties expanding our options. There are issues that come with ranked choice voting, but the biggest problem is that it confuses voters and that problem can be solved by education and acclimation.

> Voter suppression is yet another exaggerated bogeyman

Once again, experts disagree with you. I can provide sources if you like.

Gerrymandering and other forms of voter suppression have a significant impact on the outcomes of elections in opposition of the will of American voters. In short, people who would not have been elected into office are being elected because voters are silenced. Any scheme intended to prevent eligible American voters from having their votes cast or counted should be abhorrent to anyone who cares about democracy and research shows that the practice hurts voter turnout as well (people whose votes are being rendered meaningless unsurprisingly don't vote as often). For someone who seems so concerned about voter turnout you're awfully dismissive of things which would change that for the better.

I don't claim that the American people don't have a role in the decline of our democracy. We certainty have been complacent and we have allowed ourselves to become discouraged and conditioned to accept things as they are, but I can't pretend that the system hasn't been systematically refined over hundreds of years to limit the power of the average citizen to effect change or influence policy and anyone can see that what we have has not been working for us. You vastly overestimate the ability for the average citizen to enact change (see for example: https://scholar.princeton.edu/sites/default/files/mgilens/fi...) but the fact that we, that you, haven't been able to do it so far says it all. We all share a responsibility for how things got to where they are, and a responsibility to reform the system which is failing us, but if it's still possible to enact change with the system we have today it's going to be a very difficult fight.
