Love all your suggestions. Second every single one of them. My 2ct:
IMO, yeah, strikes should be reduced by better wages, not improved.
However, boosting worker laws (which do also increase wages) may increase strikes, as striking becomes easier. - Technically though, it probably shouldn’t by itself cause strikes. It should scale other stuff. If you’re angry about something, stronger worker laws mean you have an easier time getting your demands heard. If you aren’t angry about anything, you will just not demand anything, or at least not particularly strongly…
IMO, because there are such huge disparities between “regular” and “mental” health, this really should be separated out somehow. Lots of places do a pretty decent job at treating various bodily issues. But mental health very, very often gets the short end of the stick. There should be issues and policies specific to this. And Suicide Rate should probably become a stat because that actually is quite a solid, economy-scale issue in some places.
