I wish people would research economics before declaring the Labour manifesto will destroy the economy. I mean, the new deal was taught in GCSE history, the concept of government spending boosting the economy is fairly basic economics (I did it at degree level) and a quick Google will give you some good analysis by independent experts.
I've seen analysis that shows government borrowing would be worse under a hard Tory brexit than it would under Labour, evening out at around the 4 year mark then slightly higher for Labour. But with Labour there would be economic and societal gains from investment in infrastructure.
There are few people who are really secure enough to live without a quality welfare state. My dad was born into real wealth (servants, Eton, the works). Parental divorce and remarriage and early death, a major accident leaving him disabled, the death of my elder sister, the 80s housing crisis - my siblings and I grew up well below the poverty line - my mum and sister remain there. And no, a good household income in a big city with home ownership that no one helped us to doesn't feel like wealth. But I never worry about feeding, clothing, housing or even treating my kids (I worry a bit about how much I can help my wider family) and I remember just how lucky that makes me.
