The US spends around 6.8k USD/capita/year on public health care. The UK spends around 4.2k USD/capita/year and France spends around 3.7k.
For general public social spending the numbers are 17.7k for the US, 10.2k for the UK and 13k for France.
(The data is for 2022.)
Though I realise you asked for sane policies. I can't comment on that.
I'm not quite sure why the grandfather commenter talks about unemployment: the US had and has fairly low unemployment in the last few decades. And places like France with their vaunted social safety net have much higher unemployment.
