Aye mate. The country is broken and will take some fixing. As a side we need to ween people off Foodbanks and put some effort into training. A charity round my way is running eating on a budget courses and we need to put efforts into that imho.
The Laffer Curve is just a way to describe the limits of taxing. Named after an economist called Arthur Laffer. Basically, it starts with the premise that if you take no taxes at all, then a government has no money. Or, that if you tax at 100% the government also has no money, as there will be none to take, as we'd all have none left to take! This obviously implies that there is a limit to the amount of tax which a government can take. This is anathema to some politicians. Laffer tries to show that therefore there must be an optimum level of taxation. That there must be a point where taxing becomes self defeating and counter productive, and that there is a healthy tax point. Clearly, there must be such a point. Most economies, for varying reasons have a slightly different " peak" level of taxation. But none have been shown to do other than stagnate or worse at 40% or a very small bit over. Our economy, by historical examples, has thrived better at just under 40%. We are at approx 42% now. That's what Laffer was trying to explain. More taxes won't work now really.
We are short of plumbers, bricklayers, carpenters l, electricians. We need more medical staff in training and places for them when they qualify. We need computer geeks etc the list is long.... we need to ensure strategic manufacturing is carried out in the UK, in case of war with Russia or another pandemic. But what do I know
