This really isn't complex. Most of the pbvious improvements required are, well, obvious. Self-evident:
Fully funded childcare from the end of maternity leave (international data shows this more than pays for itself).
Taxing on a household basis as set out above to immediately relieve poverty for much of society and therefore improve productivity, health outcomes, GDP per capita, reduce reliance on public services/ welfare, etc.
Higher education free but fewer university places (reverse the Tony Blair effect). Then employers could not demand degrees for jobs where they are not required because there would not be sufficient graduates to fill them. Meanwhile, huge investment in technical courses and proper apprenticeships like in Germany, for example.
Support for small and medium sized businesses with much greater tax breaks, particularly for investment in technology.
Large tax breaks even for big corporates for projects resulting in technological improvements/ productivity gains. Offset by a higher general tax rate on large businesses: will not negatively affect those who are investing properly in staff, CPD and technological improvement.
Rejoin the single market immediately.
Change corporate structures so that more follow a Danish type model of co-operatives. Proven to be very effective for improving productivity and profits. Also German style system for employee board representation: results in better management, better long-term company outcomes and higher salaries for employees versus dividends for shareholders. Fewer strikes also…
Address the huge disparity between public sector and private sector pension schemes particularly in terms of the lifetime allowance calculation which is completely scewed at present.
Big investment into green energy and associated high tech jobs.
Massive investment into primary education with a particular focus on technology.
Cut back huge waste of spending on duplication of everything we used to do collectively with the EU and have now had to replicate internally (finance regs, vetinary regs, medicine approval… endless list I won’t type out).
Take the difficult decisions on long-term energy and food security that require upfront investment but are essential and will also upskill the population to fill the required roles. This should have been done when the Government could borrow at a negative real interest rate but hey ho!
I could go on. All eminently doable, fairly (in relative terms for Government) easy to implement. We don’t have to reinvent the wheel, we simply need to look around at what has been proved to work in multiple other countries and learn from it. To stop being so arrogant that our system is better. Objectively, plainly, it is not. It can be changed. The question is not what to do as it’s obvious. The question is why nobody who is complaining about the status quo is pressuring the Government to do the things that will improve things for us now and for future generations.
It’s convenient for the Government to get you to focus on the relatively petty issues that currently divide people and squabble. What they absolutely do not want is for you to look at the big picture and question why they have not done and are not doing the above, that would benefit everyone.
