On the universal benefit thing, I think we need to be clear what we are talking about.
Are we talking about a perk, a nice little thank-you to hard working folk who have contributed a lot?
Or are we talking about a limited amount of money that the government can't spend twice, so once that £1.1bn has gone on this, it can't go on other things, such as University education, the NHS, etc?
If it's the first, it would be mean to pick on the free bus pass. Of course we value what older people have done during their lives. We should make it clear that we expect the state pension to remain at a decent level, and we should fight to protect our NHS which matters to everyone, but especially ppl living with chronic health conditions, who are often older.
If it's the second, we ought at least to realise that when we try to identify those in most need in our community, being old isn't automatically a sign that you are in need. Yes, being old brings extra cost. But older people have lower housing costs if they are homeowners, and they may also have good pensions. In those over 68, like those younger, there's a big variety. You could save that capital sum by restricting free bus travel and other similar benefits to those getting pension credit- and you could afford, in that case, to make the cut-off for pension credit itself more generous.
When I retire, I think I might prefer that money to be spent in the NHs, which is likely to mean a lot more to me over the years than universal free bus travel.
