Are you suggesting Brexit benefits and reasons to be free of EU regulations??When Osborne was chancellor he paid off the final debt we owed from WW1
The notion that a country can go bankrupt is weird, since we are no longer in the EU we are not constrained by their rules and we have our own currency. We can print as much money as we like, we can borrow as much money as is needed because we dont pay it back next week, we pay it back next century and the nations assets far outweigh its liabilities so there is no reason at all it cannot be done. The Tories will be against it though on ideological grounds as they are wedded to low taxation and by raising taxation we could easily afford all the measures needed.
At the moment welfare payments are at the lowest level ever against the average wage, that could be adressed by introducing UBI, which would fuel the economy. Those with least have the highest propensity to spend and the best way out of debt is not austerity it is growth. The Tories though are wedded to neo-liberalism and its supply side measures where as we need a good dose of Keynesian demand side economics to boost the economy.
Sorry - off-topic;-)
