Again, for the third time here is the graph.
The IFS and FT and others - who actually know about economics - have calculated the effective tax rate and as stated several times in the thread that you admit you haven't bothered to read, for anybody with a child in childcare earning between £100k and £135k the effective tax rate is over 100%. I.e. those earning £99k will have MORE net pay than anyone earning up to £35k more.
If you think this will improve tax revenues to find public services, to discourage the workers who pay most of the tax from working full time, then you have no grip on reality.
Even before this budget, with withdrawal of child benefit plus a student loan, the effective tax rate for anybody with children earning over £50k was over 65%.
Even before this budget, the effective tax rate for those earning over £100k who had children and a student loan was over 85%.
You clearly have not the faintest clue about economics. These are the people paying the vast majority of the money to fund the NHS, schools, the universal credit that lets lower income households have a huge negative tax rate.
The wealthy don't fund it. There aren't enougj of them to do so and they pay much lower percentages of tax. It is the professionals working long hours who pay most of the tax that the country relies on. Screw them over even more and make it not worth their time and... well you can see what happens to tax revenues and the funding available, this is one of the main reasons why the economy is so screwed.
You've been given all the information. It's been explained to you repeatedly. You presumably have access to the internet to read about it if you wish. Your deliberate pretence that you don't get it is pathetic. Continue ignoring the issues if you wish and watch tax revenues continue to fall and look forward to yet more cuts because there won't be money to fund the services and benefits you want if you penalise the people paying for it all so heavily that it's not worth them bothering.
