You don’t seem to grasp that each of these methods has consequences itself and, therefore, at a certain point some of them become self-defeating and create worse outcomes on precisely the things they were intended to address e.g. raising national insurance on employers reducing business investment, lowering pay rises for those still employed and resulting in large numbers of redundancies and a shrinking employment market.
Cutting education budgets reduces productivity and increases long-term costs in welfare, lost tax revenue, creates lower growth, higher justice costs, etc.
Not having universal childcare provision increases welfare costs, lowers tax revenue, increases the reliance of women on state welfare in old age, damages productivity.
Having cliff edges in the tax system like the withdrawal of child benefit and the withdrawal of the personal allowance again reduces productivity (amongst the more productive members of society so even more self-defeating) because people respond to economic incentives/ disincentives and therefore people reduce working hours/ retire early/ emigrate increasing skills shortages and lowering productivity and tax revenue and again increasing welfare costs and housing costs etc. to the state.
Poor healthcare provision and the lack of preventative healthcare and screening increases the costs of maintaining a comparable level of overall population health because issues are identified and treated later which is more expensive to do and also means there is lost tax revenue and higher welfare costs to the state, etc.
Lack of investment in infrastructure and deliberately erecting trade barriers decreases investment and increases our trade deficit and makes the UK less attractive to invest to create jobs and businesses. We import a large proportion of our essential goods therefore decreasing our export markets/ creating barriers and additional costs will of course supress economic activity and lower wages because more people will be chasing fewer jobs and we will be importing large amounts of inflation, which will also raise our borrowing costs as the UK economic outlook is less favourable. Inadequate investment in infrastructure and education discourages business investment because businesses cannot rely on the skills and infrastructure being available and we have an unstable political and tax regime so they are understandably reticent to invest because there are too many risks to the long-term outcome and return on investment.
There are endless examples. It is all interconnected. It is not a question of “tax people even more and that’ll fix it”. That would make it even worse.
Productive areas of the economy must receive the investment they require (education, industrial strategy in cooperation with private businesses, reform of the tax system, and infrastructure). Directing over 50% of public spending to over 65s will not raise productivity and is not necessary - as I set out this can be changed and free up £80-90bn per year while creating ZERO poverty for any pensioner - and this could transform the UK economy over time if invested instead in productive areas of the economy and then living standards would start to rise again and economic growth could be generated.
This needs to happen and if it doesn’t then living standards relative to other countries will continue to drop.
