If the triple lock is reinstated and kept then todays pensioners will benefit a bit but future pensioners will benefit even more.
It's a bit short sighted to argue for its removal because some pensioners have more assets than most young people.
I agree that the putting the fiscal burden on working people is unfair. But there are a huge number of pensioners whose only income is the state pension.
Putting more of them in poverty won't help the people on lower benefits or in low paid work. It would also mean that those people have poverty to look forward to in retirement.
Raising benefits and wages would help.
Reducing taxes on earned income and taxing capital gains, unearned income and wealth is a much better answer than fighting for a bigger share of the crumbs.
Here's a pension inequality for you: if you die with unused pension funds, they are outside of inheritance tax. So you can accumulate wealth tax free and pass it on tax free so long as you have enough money to do that. If you're properly rich you can live off your iht estate and not touch your pension.
Let's get that money in the system before condemning ourselves to poverty out of envy.
