Labour's plan to build lots more housing, especially social housing, set out in detail here. Pennycook also did a thread on BlueSky which provides a handy summary.
So, in summary (with links to relevant bits of the thread): £39bn for a 10-year plan, aiming for 300,000 homes of which 180,000 will be social housing. The £39bn includes skills training and low-interest loans for social housing providers.
They're going to reform (not abolish, unfortunately) Right to Buy, so that homes are less discounted, tenants will have to wait longer before they can buy the homes, and those in new homes will have an even longer wait - 35 years before any of those 180,000 projected new homes can be bought under right to buy.
I often wonder about this with regard to right wing Americans believing such ridiculous things. It's seem that what Trump supporters ultimately have in common is not one set of beliefs but a shared belief in things that make no sense: that all Democrats are paedophiles, that JFK wasn't really assassinated, that vaccines don't work, that climate change isn't real, that Donald Trump is anything but a foolish, evil corrupt man. What do these views have in common? They're fundamentally foolish things to believe.
The fact is that once you believe one patently absurd thing - for example, that an interventionist god exists - your thinking gets warped. When you then make this absurdity the centre of your worldview and your identity, your views on everything become warped. After a certain point, they seem to start believing things because they make no sense.
If a person believes God actually answers prayers, something there is no reason whatsoever to believe, they're primed to believe all kinds of other nonsense. This is exactly why many religious people have stopped believing in that kind of thing, and now take refuge in the idea of prayer as comfort or as asking for 'strength' rather than asking for anything specific (note that even this compromise requires them to ignore the plain meaning of the words of, e.g., the Lord's Prayer). Most people find it uncomfortable to believe in nonsense. For others, it becomes the point.
