Already mugged of savings income due to unfairly low interest rates, they now want the generation who have had it better than previous ones, due to accumulating wealth in the country over time, to be able to grab even further finance from the older prudent generation to gift to themselves.
The property ladder may be a little more difficult to get onto now, but it was never easy nor without sacrifice, and present issues would cease if we stopped increasing the population year after year and expecting to resource the continuing growing demand.
I think some think tanks get caught up in agreeing with/backing up other members of their group, and encouraging their suggestions, whilst forgetting to check with reality and the consequences of their wild flights of fancy.
This won't help social cohesion, it's divisive to abuse one section to gift to another, will exasperate any differences of opinion and accelerate any widening gap.
