Like the idea of early diagnosis, and check-ups. But that does mean a lot of people who don't need anything clogging up the system. I'd settle for the NHS and doctors simply having enough time to deal with the people who want a check-up and currently get 10 mins on the conveyor belt if they are lucky! Never used to be like that.
Growth equals more money. Growth stimulates the economy and gets money flowing. Stagnant money stops prosperity. That activity then generates money for our government to spend. If people are sitting on money, there is no tax on it. If things go backwards or stagnate then there is less money for the government to spend. What does that mean?
Just look at the financial crisis 10 years ago. Cuts to public spending. Teachers and nurses having their pay frozen. Less money to invest in health care in the UK. Less money for everything. I believe you can evolve the economy in some 'marxist-like' ways to create more free time, without taking the UK backwards and harming public services. France does a decent job of it for example. Since the pound was devalued their economy is larger than our own (just) but they work a lot less than we do.
But lets be clear, the slowing effects on our economy post brexit vote, have slowed tax receipts. Have slowed the amount of money our government has to spend. Borrowing has increased. Interest that tax payers are paying has increased (£40b a year we pay in interest each year!). Under Boris' plan, there is every indication that this trend would accelerate as we harm trade with the EU, and no evidence what so ever that we would generate more to make up for it. That translates as less money for nurses, hospitals, schools and everything else the governments spends on. How could anyone want that?
