I think a core difference is when it comes to spending and the national debt. While I'm actually a moderate, I do understand that moderates and centrists seem to be just fine with the staus quo of adding even more onto our 36 trillion dollar national debt. Don't make waves, compromise, be nice, and let the debt just grow and grow. I understand more and more that many of those "extremist" righties are tired of no one addressing our runaway debt and are willing to be hardcore in fighting it, even if they have to burn the house down in order to do it. I'm that moderate who also wants to get our finances under control and it is about time someone gets serious about it instead of more of the same ole same ole compromising that continues to add onto the national debt.
I don't go for this. When Republicans are in charge, they spend lots and try to cut the taxes of the rich significantly, underfund the IRS, which requires more funds to find tax fraud of much wealthier people, and refuse to close tax loopholes for the latter. This ends up creating more debt.
When Democrats are in charge, Republicans then spend tremendous amounts of time screaming about the debt, which they themselves ran up, and how we can't afford the social safety net, but don't do anything about the extreme military spending and tax loopholes of the rich, etc. If Democrats call for focusing on collecting on the tax fraud of the rich and closing their tax loopholes, the Republicans yell and scream that Democrats are the big spenders.
Frankly, at this point, we need a serious wealth tax, not a mere increase in income taxes of rich corporations and people, because the extremes of wealth and poverty hollow out the middle and threaten healthy democratic functioning.
We should have accepted the Biden-term IRS funding increase aimed at finding and prosecuting the tax fraud of the wealthy, and also closed the tax loopholes. We should avoid war, streamline military spending, and root out waste, fraud, and abuse as was done in the Clinton era when Clinton's VP, Gore, worked on that problem successfully.
But it is ridiculous to suppose that programs for the social safety net, which takes up way less of the budget than some other parts, Social Security excepted, should just be junked. Trump has done so far been very careless about his firings and cuts to programs, which may end up costing us more.
So that's how I see it - the Republicans want to help the rich, don't care whether or not they make sick people sicker or disabled people die or have poor people evicted from their homes, spend money like water on things like the military and war, which destroy the fruits of labor. The Democrats clean up afterwards, not so much as to play Robin Hood, but to make ordinary peoples' lives safer while letting the rich be prosperous, too. And the Dems do cut the deficit - in Biden's term, it was just really hard to do so quickly because of COVID, which wasn't his fault, as it arose under Trump.
I'd probably prefer democratic socialism, especially after the housing crises, including the current one. Many wealthy real estate corporations don't care if they make 50% of the nation homeless, they want "money, money, money" for poorer and poorer service. If they can't do better, there should be a government takeover.
