I absolutely get the point the article makes that higher earners are not seeng the benefits. These are people who are working 12+ hour days to work their way up the corporate ladder, but not seeing a noticeable change in their lifestyle. There will of course be the 'boo hoo, cry me a river, diamond shoe too tight love' comments, but this is a very real issue, not for them, but for the country as a whole. Most of us rely on the smallish number of net contributors to cover our healthcare etc, so we need then to stay. But why would they, when their skills earn a much better lifestyle abroad. Taxing 25% of 100k gets us a lot more than taxing 40% of nothing if they leave.
Very few of us are net contributors. DH and I earn about 90k between us, pretty decent it would seem, surely we are net contributors at that amount?
Of that, we pay around 20k in tax and NI.
We have 2 children in school, each costing country about 6k, plus they get the infants Universal free school meals - £800 per year
Universal child benefit for 2 children - about 2k per year
I get PIP - 4k per year
So without even factoring in our nhs costs, of which we all have some - DD and DH are coeliac, I have arthritis, other DD has some health issues, we are net takers.
Very few people are in reality net contributors, and without them we will lose access to even basic free heakthcare, schooling etc. As someone said upthread, we are a poor country perceived as rich, we are hanging on by a thread.
