It’s a tough argument. The liberal position is that govt should provide high quality healthcare and public education. But look at their record. Do you want the the medical system to be run like the crappy DMV? We pay more for public education than ever before, and quality continues to go down.
Public housing? Remember how bad that turned out? Amtrak?
Would these all be better if simply poured more money into them? No - it’s a management issue.
I just bring that up since you advocate the govt taking a bigger role in transit. Look at how poorly California handled the high speed rail project. Now scale that nationally. They just can’t get it done.
Even Democratic-dominated Nashville voted down a big transit bill as the public saw how the numbers were impossibly low-balled. No one wants to own a boondoggle that will not really solve the transit problems. Faith in govt is not high. Perhaps a private/public model like SpaceX / NASA would work for space transit. That’s working a lot better than the pure govt approach.
Another good one is the privately funded Texas High-Speed Train:
Commuters between Dallas and Houston could have a less expensive, more convenient alternative to flying by 2025.
The company behind a proposed 90-minute bullet train, Texas Central Partners, is waiting on a finalized environmental impact statement and record of decision from the Federal Railroad Administration. With a nod from the FRA, construction on the train—the first of its kind in the U.S.—will hopefully begin this year, Vice President of External Affairs David Arbuckle said at a Jan. 16 Growth & Mobility Luncheon hosted by the Richardson Chamber of Commerce.
So far funding for the train, estimated to cost between $12 billion and $15 billion, has come from private investments, Arbuckle said. A bill passed by the Texas Legislature said no state money can be used to pay for the train; however, Arbuckle said Texas Central can coordinate with the Texas Department of Transportation to make the train a reality.

Also there’s the Florida project being developed by Virgin Trains USA (formerly Brightline).
They predict service between Miami and Tampa through Orlando has the potential to carry 9.5 million passengers annually.
Brightline-Virgin service also could achieve what Central Florida leaders have been unable to solve: establish a link between SunRail commuter rail and Orlando’s airport.
To develop service between Orlando and Tampa, the privately owned and operated Brightline is now negotiating with Orlando Utilities Commission, Central Florida Expressway Authority, the Florida Department of Transportation and with private landowners to lease or buy land for rail and stations.

I’m just mentioning some examples. Virgin Trains could do the Charlotte - Raleigh high speed route.
So what about the Triangle? I don’t know if any private entity is looking at a dense commuter path like UNC/Duke/RTP/RDU/Raleigh. I wonder if Virgin could find this route doable if public money made up the ‘non-profitable’ difference. Could be more viable than the last attempt by govt entities alone to pull off the project. Are residents ready to see transit like this operated by a private company?
