You seem to have a very poor opinion of the generations who will be bearing the brunt of the cost of fixing the chaos the tories will leave. Don't you have any kids of your own? What do they say?
There is not a single cause of our problems, it is an unfortunate accumulation of problems that started many years ago and then Covid took everything to a new level, Ukraine has not helped and this has left the conservatives floundering in the mire with insufficient funds to do much with unless they raise taxes or cut spending. Whatever party takes the wheel they will still have the same underlying problems and huge national debt so to do anything will raise taxes or cut spending and it is just a question of which and where.
These generations should not be shouldering the debt due to covid, we do not need to just continue in the same rut and doing the same things because we just go round in circles, to fix a big lot of problems you need big changes in many areas such as the civil service, house of lords and the NHS whilst not thinking that money will fix our NHS, the magic words are efficiency, economies of scale and re-organisation. How many people believe that an MP is on the right money for the job along with expenses yet a nurse does not deserve a decent payrise, they are out of sync along with many other jobs.
My daughter is a nurse, fed up with the profession due to so many nurses having quit or emigrated and just puting the pressure on those left, a decent payrise would help but also re-model the nhs to meet the modern demands and give them a decent well equiped place to work where patient care is number 1 rather than targets and get rid of the overpaid paper chasers doing bullshieete jobs.
If you recall the eighties then labour were in a right shambles, leaving the tories free to do as they please and then after blairs reign house prices had risen much faster than wages and in some circles blair is attributed with the current housing crisis where people cannot get on the ladder so Labour + Conservative = zero and neither is better or worse than the other and both are never going to deliver the promises they make because based on past history they never have and until the political system is reformed nothing will change.
Point is: you're predicting the end of the world but for the life of me I can't see any specific evidence to explain that position.
No, the continuing decline of the UK unless massive changes happen for the better, nothing is saying this will happen following the election because neither Labour or Conservatives are being open and honest, the greens will have us in darkness due to carbon zero and Lib dems are just there for whatever reason.
Now as for the end of the world we have not been in such a position since Cuba, the old clock is just 90 seconds away but unlike then we have some really bad leaders with no skills in diplomacy and people like cameron are just not helping whilst having a geriatric US president is un believable. His son is in trouble for guns whilst not declaring his drugs issue yet his dad can have a nuclear arsenal and on some days be non compos mentis ! So unfortunately tommorow is not a given until we wake up and start being nice to each other and condem both war and nuclear, chemical and biological weapons.
