No, I am trying to get people to think about how the state pension, which started off as a sensible scheme, has been perverted and promised to so many people
That was how it was designed and it's still doing exactly that. So there has been no
perversion (sic)
(I suggest you check the definition of "perverted")
and that this is probably why it is unsustainable.
That is why the government are tweaking it.
I am not offering a solution, just trying to make people see a truth that is currently outside the Overton window
So you're bringing to the public's attention what you think is a problem? OK, you've done that.
But you've misunderstood the Overton window. It does not refer to "problems", it refers to "solutions".
If the solution is outside the Overton window, it will not receive public support.

e.g. The problem (whether it's true or not is debatable) is too many prisoners for the prison capacity. The proposed solution is to begin a mass execution of prisoners.
Ah! That's outside the Overton window. D'you see now?
It isn't the problem that's outside the window, it's the proposed solution.
Mottie was wrong. His information was out-of-date.
I've described the NI credit and 0% band giveaways, but these were compounded, and then some, by pension credit,
Pension Credit is funded entirely by taxes, and not by NI.
which does not apply to those who have worked for their pension,
Of course, if they qualify for a pension, they're not entitled to Pension Credit.
but entitles those who haven't to a sum equal to it,
You're wrong and also out-of-date, based on Mottie's incorrect information.
and qualifies them for housing
No. They may be entitled to assistance.
No They may be entitled to a reduction.
Wowee! But all pensioners over 75 also get this.
travel costs for hospital appointments,
So can a range of others, e.g children, UC benefits, referral to specialists, etc. Do you really want to deny this assistance only to pensioners?
The additional administration would probably cost more than any savings.
All pensioners get that, and it was discussed in detail previously. It was decided that if it was restricted to only those on low income, the admin cost would be greater than any savings. Why do you think the reverse will be any different?
help with sight and dental treatment,
Everyone on low income is entitled. Do you want to deny this benefit to all on low income?
Most pensioners get the same support, so there's no or little difference being on Pension Credit.
Such as?
They may not have been doing nothing, they may have been a homemaker. (you'll probably have to look that up)
Furthermore, any UK resident can get pension credit -
Nonsense! They have to be eligible.
yes, this includes foreigners who have only recently arrived.
More nonsense:
Both Ivor and spineless spout a load of nonsense over things they have little understanding,
In the process they display an utter cruelty to the treatment of low income pensioners, and other people unfortunate enough to be on low income.
