That’s a major problem, I agree. But one of the reasons is that incomes in that lower / middle bracket haven’t risen as much over the last 20 / 25 years as you might expect. And I think there are two reasons for that - the in-work benefits culture was originally an attempt to massage the unemployment levels under the Blair government. But what it has actually done is depress salaries / wages for everyone, including those who don’t qualify for those benefits, and created a huge transfer of money from the (originally Labour) government to the private sector.
Then the massive increase in the number of young people going to university, again to keep unemployment levels low in the short term, without investing anything to increase demand for graduates, also depressed graduate salaries for one, if not two, generations.
So we now have the perverse situation where a newly graduated young person from a middle of the road university with a middle of the road type degree earns only 10/20% more than minimum wage, and career progression for them, plus all those who leave school and don’t go on to university, is really really tough. In real terms their income increases at a glacial rate.
In the mean time because no government for 40 years has invested in social housing these working grads are competing with those on benefits for an ever shrinking pool of houses to rent. It’s no wonder rents have skyrocketed…and the stupid thing is that the politics of envy means that the private sector is also disincentivised from filling the gap that government / local authority have created by not investing in social housing / houses to rent. So now neither the private or public sector are investing in properties to rent. Which has exacerbated the problem further. Now, this government has said it wants to supercharge house building. But it hasn’t said how it’s to be funded, and if they expect the private sector to fill the gap then they’ll either need to change the tax system, or create further subsidies, funded no doubt by PFI or off government balance sheet finance at higher than costs.
