We need someone with vision. Someone who can see past a 5 year term, who really thinks about life in this country.
Projects that cost billions of pounds should be overseen by an anti corruption watchdog to make sure the money is spent wisely, and doesn't end up wasted (there is so much wasted money on these expensive projects, largely due to corruption. Ppe in the pandemic is a brilliant example, as is test and trace). In fact as pp said, all public money should be spent in this way, checking that it is going where it needs to.
Then, all social initiatives, whether it is housing, schools, benefits, the NHS need the cash they need to make them functioning and world class (the money comes from the previous point). This should give children brighter futures, help with knife crime and crime in general, because everyone should have opportunity and prospects and enough money to live.
Then, finally, we tackle climate change. I know kne country going all out isn't a magic bullet, but so what, why should that stop us leading the way? Green energy, better public transport, new infrastructure projects where for every metre of concrete poured, trees are planted or a metre of wildflower is planted. Creating jobs, and a real sense of the future being possible for the kids.
Pie in sky stuff, but that's my take on it. Radical rethinking. Oh, and tax the shit out of the super rich and companies. Close that disgraceful gap.
