This is such a non issue. The more important issues are the under supply of housing, affordable and social for the last 40 years, alongside high rents with some bank rules like the landlord must charge rent in excess of at least an extra 35% of the mortgage and foreign ownership leading to empty buildings in major cities.
Not to mention over 1 million homes owned and empty in the UK.
If just these things were tackled then there would be no high prices in some areas and indeed no housing crisis. Some areas would still have high prices due to location and desirability.
Government will not build no matter what they say in their manifestos, the last ten years have shown this. Also local councils and housing associations have been willing to build but are legally not allowed to raise the necessary money by the government. You really could not make it up.
We need to go back to most rental properties being in the hands of local councils and housing associations with a private rental system alongside but a smaller one and not the current one that we see.
Then people would pay a fairer market price depending on size and location like before, not just an overamped price.
And people need to stop judging the entire UK by London. Even the whole southeast is not expensive like what people make out. And across the country some places are still at pre 2007 prices. The entire north is not cheap like some people make out.
Why should family not help out? That is their choice and it's not just a middle and upper class thing to do, working class families help out their kids when they can afford to and want to do so, also and in some areas they can afford to still. Helping out your children is not even a class issue, it's a thing that some parents do across the board and why shouldn't they?
Low wages should be addressed and high rents but a parent should be allowed to help out if they see fit to.
Some parents pay for school trips and holidays, some will not deem these necessary. Some wouldn't want their kids back home after uni or past age 16 /18, each one is different in the way they parent, why would money and housing be any different? And why be jealous of the ones who get help?
Sort out all the other issues...
It like saying it's unfair that he gets paid 70k to your 35k. You simply have to accept that some people get paid more and hard work is not consumerate with high pay. So also accept that some parents help out their children financially. Remember not all richer people help out their children and not all poorer people cannot do so. Some people on low incomes go without to help out their children, whilst others do not. It a parent thing and not an income thing.
