I used to have a similar view of my position in the economy when I hit hard times.
I mostly use private medicine and in the past used to comment that I don't benefit from the NHS.
The thing that really changed my mind was when I got to an age where friends and family started to get cancer and the NHs spent literally millions of pounds keeping the people close to me alive.
They spent over £2m on Rowhan alone.
For that reason, I walked away from Tax avoidance and have been paying maximum possible tax on my earnings since.
My old opinion was an incorrect one. Every penny I contribute is a penny well spent.
