More than anytime in US history, this country needs a long period of cooling off, healing and reconciliation. A sudden lurch to the far left, while desperately needed in multiple areas of domestic governance, would result in an even more violent backlash, making a number of reconciliable differences totally impossible to resolve.
A boring centrist, moderate government is what the US needs right now. A coalition of center/left and center/right is IMO the key to re-marginalizing the right wing crazies that have risen to prominence under Trump. Only then can real, albeit incremental progress be made.
I'd like to agree, but I think you're mistaken. I believe the root cause of Americans' division is the fundamental insecurity at the heart of American life. Unless you have a million or more in net worth you have no financial (or life) security. An illness and / or a job loss will wipe out most Americans, and there is a coming tidal wave of elderly poverty as soon as the generation with final salary pensions dies off.
Moderate / centrist tinkering around the edges will not fix this. Should the annual deductible be $12k or $15k, and should ACA subsidies end at $60k annual income, or $75k is not going to fix this. We need bold actions such as
- repeal the Trump AND Bush tax cuts.
- reduce military spending
- Medicare for all OR price controls (e.g. no provider may charge more than 100+X% of medicare).
- Federal drug price controls or negotiations (perhaps QALY based)
- Replacing 401k/IRAs (which is just an vehicle for Wall St to fleece the middle class) with a not for profit or government retirement plans - perhaps a parallel to social security that is allowed to invest in the markets.
- Public education through age 21, academic or vocational (since this is the minimum requirement for the modern workforce).
- Strong federal gun control laws.
Many on the right will scream bloody murder as this is enacted, but give it 5-10 years and Americans will love being able to access healthcare without fear of financial assault. They'll love being able to contemplate not living in poverty in their older years. Just like Americans love Social Security and Medicare, both of which the right screamed would turn America into the USSR. The right wing is so scared of government programs that serve ordinary citizens because once they're enacted they're very popular and very hard to undo.
Until Americans have a similar level of life security to Europeans, Canadians, Australians etc etc it will continue to be easy for the right to foment culture wars.
