Norah, if people can't afford to pay full pension contributions, being able to pay into ISAs is unlikely to be the solution. It may be simple, but it's not for everyone.
The problem, IMO, is twofold. The first thing is that wages in the UK are low, and if there is a move to raise minimum wage upwards there is an outcry from those whose profits depend on others working for little. This means that there are many people who can't afford to pay into occupational pensions, so rely entirely on the SP.
The second problem is that after decades of the welfare state picking up the tab for those who choose not to work, a pension is seen by many as a right of passage - you reach SPA and you are paid for doing so, regardless of contributions. This attitude is being challenged, and the narrative now is that people have to pay in to get back (the same narrative that is used about people claiming other benefits).
As we are now an ageing society, pensions are expensive for the treasury, and whereas it would be lovely to be able to pay everyone a decent income in retirement, there has to be a difference between those who have paid in and those who haven't. If that difference is not there, resentment and accusations of there being a 'two tier society' ensue. Nobody likes seeing others being given what they have had to work for.
Things are complicated, however, by the fact that older people have to live. If they haven't made provision for their older age they can't be left to starve, and the added benefits of being on pension credit mean that they are brought to the same level (or often higher) than those who have a small occupational pension, and we are back to the resentment and accusations. The social care system makes things worse, as those with relatively small savings see others with none getting free care while they have to pay until they, too, have nothing.
But what's the solution? To bring back workhouses or other punitive measures to force people into saving? There will still be the problem that not everyone can afford to save. Let people starve? Not something most of us would like to see. Make people work until they die? That is already happening in some cases, and younger people who realise that this is likely to be what they are facing are even less keen on paying taxes for older people who may be better off than they are. Renege on the 'deal' (and yes, I know there is no written contract, before someone rushes to point that out) that if you pay in you will get a pension, and means-test the SP? Why would anyone bother to pay in that case? Of course most of us have no option - it is always those on PAYE who underpin the contribution system - but there would be widespread fury and discontent.
It's a thorny problem, which is why it hasn't been solved before now. Up to a point, the 'if you pay nothing in, you get nothing out' is 'fair', but unless there is a massive change in the way the UK has operated since WW2, that will always be weakened by the fact that we don't want to see people starve or go without essentials.
