My parents didn't get hand outs, my mother in law worked 3 jobs at one point to give them what they wanted. Did they moan about it? No. My parents are close to retiring (1 already has). My Dad worked from the age of 16, planned wisely, never out of work, they have done very well. Yes they have property which is now of good value. Why would you expect him to pay more NI, when for the last X years they have been.
Why would you expect those 65+ to not pay NI? Is any tax of those who are retired acceptable? Or just NI? Or is it just taxing those 65 and above for social care? I.e. those eligible. I personally think it makes perfect sense for everyone receiving an income, regardless of age, to be taxed at the same rates. I'd take it further and abolish NI and change the tax bands to what they actually are, 32% and 42%. Capital gains and income from property rentals will then be captured in this.
