there never was a magic money tree, it’s an incredibly difficult balancing act of meeting all needs. Short term needs where people will literally die or suffer now eg hospitals, homeless, care versus the medium/long term. With public sector wage demands etc. Aside from fiscal matters, in an increasingly risky world eg Putin, OPEC playing games, energy security is required.
This is probably the most succinct summary I've read as to why being in government (any colour) is something of an impossible task. I don't know what the answer is but if we, as a society, expect government and the taxpayer to do everything we individually think is important or our own priority we are simply setting up every government to fail and in turn so will our society and arguably so it is.
