But really, what's stopping us from funding public services properly with the economy as it stands, today? Inflation aside.
Government debt repayments, government bad choices on what it's spending it's money on, corruption, flat out fraud, bad management. That's just this government. The problems go backmore than a decade.
Is the only way to maintain our public services to have infinite economic growth? That seems like a hard sell, to me. There must be a better way.
We have a higher population right now than ever before but also the highest amount of tax being collected by the government ever. At the same time we have a hilarous government debt level and it's only now just starting to become possible to borrow again at acceptable levels, after what Truss did. Local councils are stuck with ridiculous loans they had to take out (to continue operating) at stupid interest rates.
UK's productivity is still shocking. If it was much higher you'd see more money being produced and more taxes being paid.
Top businesses in the UK pay silly low amounts of tax. That's not an easy fix in this globalised world but it needs sorting out.
UK long term sick numbers are huge - 2.6 million (because in part of NHS waiting lists and the hang over from covid).
Young persons signed off work for mental health reasons seem to be ever increasing.
Look at many Nordic countries (highest quality of life, highest tax levels, fully working public services). They are still highly capitalist economies but they have made decisions that means their countries (generally) work for more people.
You need a fairer society but most of all you need a competent government making good decisions. We haven't had that for a long, long time.
So yes the country can work again, public services can be funded properly with the current economic levels we have. Growth is desired / needed by pure capitalism .. but it's the best system we have, despite not being perfect. Additional growth ignoring the above fixes, means you'll of course naturally have even more money to fund things if you decide to. Considering we don't live in some kind of Star Trek utopia, a more Social Democratic kind of government is the best option IMO.
