Interpret improvements as you like. For me it’s any large scale reforms or legislative packages designed to improve the country for all or see to the material interests of the majority without overly benefiting the elite.
Any big consumer protection, environmental, infrastructure, or other legislation from Clinton onwards that materially improved the lives of all?
Obamacare and the medicaid expansion comes to my mind. It has obviously improved people’s lives but considering how broken the healthcare system remains, and that it was written by the insurance industry to undermine single-payer, it seems to me a mitigated win at best.
Gay marriage and marijuana legalisation but that was the courts and the states although i’m sure the federal government could’ve stood in the way had they chosen to.
I’ve only live here since the 2010s so that’s all I can think of.
We had something similar to get people to by electric cars where I live. It was removed some years ago, and what I remember most from that is a woman on the news talking about how she just spontaneously bought a new car before the benefit went away, just because why not the benefit is going away soon might as well just buy a new car.
