What a load of rubbish. HTB really helped us when buying by giving 5 years of interest free
We bought a 240k house with a 12k deposit and 48k htb. Moving costs etc meant we had to find about £17k, which we borrowed.
Assuming you do that now, HTB means paying £647 a month on the mortgage and £330 a month on repaying the deposit. Total of £977pcm.
After 5 years we sold for 240k with £48k htb and £160k mortgage, leaving us with 32k in equity. We could have remortgaged and repaid the htb at that point for a total outlay of £911pcm (with about £500 in fees)
With two earners on a middle 28k a year that's falls into well into the "affordable" bucket.
Even in London, a 600k house with htb will mean a £30k deposit (a problem) and a £330k mortgage. Two people on 41k each can borrow up to £368k with nationwide which gives an idea about affordability (you'll have to knock some off for things like service charges which are ubiquitious in new houses)
And 41k a year with a coalition loan means you have £30,310.51 per year after student loan, not before. If you still have a labour loan from pre-2012 you'll be paying an extra £600 a year.
All that's assuming a 600k loan. Reality is that help to buy homes aren't that expensive. This is a decent sized 2 bed flat for £375k.

Personally I think you'd be crazy to live in London when there are far more reasonable places to live just half an hour out of a one 1 station and far far less cost, but it London is affordable for people with two London incomes.
If you're single on minimum wage and wanting to live in central London? Well tough. Move somewhere else. Plenty of choice for houses in Crewe and Stoke, and plenty of minimum wage jobs.
