Nice moving the goalposts. I assume you’re from the US, where is your effective liberal party? That has a seat in federal government that is able to effect any legislative change?

Leftists, especially social democrats, but even socialists have been in government and have passed legislation that created systems like universal healthcare, unemployment insurance, family allowances, pensions, maternity leave. Just not in the US. The reason you don’t have all that is because you spend more time fighting against progressives than doing anything else.

And gloating as a liberal that “well, progressives just can’t get into government” after making such a shitshow of governance and campaigning that you got Trump elected twice is ghastly.
