I'll expound on my previous post to Skroe. As in California, the solution is to get 60 Senators. Maybe this can't be done by 2024, but definitely by 2028 (possibly by 2026). Once California got enough democratic votes so that republicans could not block their bills from passing, California fixed a LOT of their problems. The US has to follow that same path.
Orange County is turning blue. NC and GA are two states that are prime to switch. And others can happen as well. When Obama was first elected, he actually had 60 senators for a short period of time. So it's happened once, though only for a brief time. Now it's time to make it a permanent feature.
Republicans have had a lot of power since 1980. Since then the US has slowly decayed, and in the last two years of Bush it quickly decayed. The last two years of Bush were very bad for the US, especially white males (it was called the Mancession). If Trump is reelected, which I think is about 80% probability, then I believe that the last two years of Trump's second term will be about the same as the last two years of Bush's second term. Very bad, especially for white males.
To achieve the goals you have discussed, it seems to me that the following has to happen:
Warren (or someone like her?) has to be elected. She uses the first 4 years to create blue prints of which versions of which plans she wants enacted. In 2022 and 2024, a HUGE amount of attention is spent towards flipping Senate seats blue. We get to 60 by 2028 or your vision just won't happen.
In 2024 she will face charges of being a do-nothing President due to being blocked by republicans. But she perseveres, wins reelection, and in her second term (or in the first term of her successor), good things start to happen. Exactly as you are talking about in your post.
Look to California to see the results. California is doing better than most states in creating jobs and in creating wealth. It has its dirty laundry plastered all over the news. The governor of Texas worked hard to convince California business to move to Texas. And some did.
This is what the US would be like. Conservatives will scream bloody murder every step of the way about how horrible this all is, just like they did against Obama. The business community will threaten US jobs repeatedly. But yet California is still doing pretty damn well.
California has forest fires, and Trump publicly complains about their forest fire fighting abilities and how corrupt they are. Alabama has tornados and Trump talks about getting them A-1 service from FEMA. Conservatives will pull out all stops in defeating this. And the battle has to be fought.
