I don't hate taxes I know how important they are for society, I'd be quite happy to pay more IT to fund the NHS as it's hugely unfunded and in a mess. But that is another thing.
NI I now feel is a lie that MP keep up the facade with and like to keep kicking it down the road for someone else to deal with. Everyone paying NI now is unlikely to get a state pension as it increases and is quite possibly means tested away. This is likely to affect the younger generation the most.
I'd much rather NI and IT were rolled into one. My parents both retired and higher rate tax payers from their pensions and property, but yet in the current system they don't have to pay any NI. As a result of the poor NHS they have had to have several opps done privately. So they would benefit from paying more tax and having a NHS that is fit for purpose.
