1. Social Safety Net
Social security has been one of (if not the outright)
most successful government program the US government enacted. It has prevented tens-hundreds of millions of senior citizens from falling into really bad poverty. One can only look at the effects of the great depression on the elderly and how the worst effects of every recession since have been blunted for the elderly and most vulnerable to see how successful that was.
2. Healthcare
Medicaid and related programs have been a lifeline to senior citizens and other qualifying citizens and
saved lives. The profit driven
healthcare system in America is proven to be a disaster. It costs more on a per person basis in America compared to countries with socialized medicine, America has hundreds of thousands of bankruptcies associated with the for-profit system and failure of the US to have healthcare in line with comparably wealthy nations has been
well documented. Even
honest libertarians will acknowledge that there should be nationalized coverage for catastrophic, chronic and terminal conditions.
3. Taxing strategies
The most successful period in American history economic is post-WWII to the early 1970s. This was in line with the highest tax rates and lowest inequality. Its been
proven again and
again that the GOP rhetoric that "tax cuts pay for themselves" is completely false. Not only has the GOP tax cut strategy been an economic disaster but contributes immensely to the
increasing inequality that is exceedingly harmful.
4. Environmental Issues
Let's put aside climate change for a minute and just look at the basics. Conservatives want to deregulate industries and allow them to self-regulate. Yet that has proven to be a disaster (fatally for many citizens). Just some examples include
Dupont dumping toxic chemical PFAS and
avoiding responsibility,
Dow Chemical dumping toxic wastewater in Michigan, and a report on all the
toxic dumping of chemicals by major corporations acting within conservative deregulation schemes. It should be blatantly obvious we need regulation on environmental issues because of the inherent
economic problem of negative externalities not reflected in the cost of products and the price ultimately paid by citizens and government. Even a cursory look at history, not even taking into account the problem of climate change, shows the problems with conservative economic policy in regards to the environment.
5. Voting rights
This should be self-evident why access to voting is "provably good". Voting should be equally accessible to all citizens. Yet the GOP
again and
again is trying to suppress voting rights meanwhile propagandizing
lies about voter fraud as a reason for voter suppression.
6. Civil rights
This is another that should be self-evident. I don't need a link to prove that Jim Crows were bad, the Chinese Exclusion Act was bad, vagrancy acts (and more) were bad, etc.
7. Guns
I think the gun crimes in America compared to Australia and the UK demonstrate how much better gun regulation is than allowing people unfettered, unregulated access to guns.
There are more issues here I could write pages on - the benefits of regulation vs. right wing unregulated economic disasters, why abortion rights are necessary and provably good for society, why the wealthy should not control politics, etc. I would instead ask you to provide proof that any of your conservative policies have been "provably good" for society.
