Ergo you introduced the poverty element. I pointed out that the average pensioner income is £15k - an income on which most working people would be entitled to benefits.
You also said how poor do you want them to be, which is about poverty, which means you absolutely did make a poverty argument. There is no other possible interpretation of what you meant.
Also, the bit about most working people being entitled to benefits on this income is a new introduction. That would depend entirely on circumstances, for example assets held.
So essentially this is a pointless argument. If the average pensioner income is £15k, of which £9.4k is state pension, the average pensioner would still pay nothing.
Do you think people are taxed based on the average income for their age cohort? The personal allowance is 12.5k, which is less than 15k so the average pensioner would still be taxable even if they were. Everything about this way of framing the issue is wrong, but then that's probably why you've been unable to understand the point.
There are people who have income that wouldn't have been included in the proposed NI increase. The proportion of working age people in relation to the number of pensioners is much lower than it was several decades ago, and even lower when we factor in those working age people whose income also wouldn't have been caught by NI. If we want to fund the NHS properly, we are making it much more difficult if we decide to opt out whole cohorts regardless of their income level. None of this is remotely a matter of opinion, some of you have just decided that the impact of demographics is negotiable.
