I can appreciate your sarcasm.
All those things you listed sound wonderful indeed, who wouldn't want them?
The first 3 things you listed unfortunately would require personal responsibility from the citizens to work properly. Accessible affordable healthcare will ultimately crumble if people rely on outside entities for health, while continuing to dig their graves with their teeth, engage in substance abuse, and totally disregards their bodies, because, hey, health care is free or affordable.
Expanded family leave. Who is going to pay for that? the company that has hired the employee? the state, the feds? Most likely, the taxpayers...
Improved social safety net. We have had social safety net for decades, it's called welfare, and we have had people who have made welfare generational starting when they were teenagers. Their lives did not improve.
We have Medicare. We have Medicaid. We have Social Security. All of these on the taxpayers.
I guess, it could always be improved. But how exactly? what more should the government do? Who is going to pay for more programs?
Racial equity. I love that term, because it is so vague. How exactly is the left going to make "racial equity" happen? A lot of the riots happened in states and cities ruled by.....drumrolls... democrats, most of them positionned on the left, as in Major Durkan of Seattle, who allowed CHAZ/CHOP to take over 6 city blocks and dubbed it a block party and the Summer of Love! That is, until they brought the pitchfork to her doorsteps.
Reduction in gun violence, gun death and mass shootings. Ok. Lofty goal. I want to see the left fixing Chicago's South side gun violence issues first, then I will believe they can solve the issue of gun violence.
