I take it that you haven't Googled house prices in the LBB. I don't know why you should think that I 'clearly have no experience' of these issues. You're wrong on all counts.
I live in Bromley and have done since 1972. I frequently travel to central London and fast trains to Victoria do take 15 mins. Look it up. I can be in St James' Park with my dgd in 45 mins, door to door, including a bus to the station.
I've no doubt that, if you lived in Bromley and worked in, say, LB Hillingdon, a commute might well take 2 hours each way. But why would you? I used to work near Oxford Circus. Central London by any definition.
London is a big place. Even in a Tory borough like Bromley, there are cheaper areas and cheaper properties where a commute to Central London doesn't involve the 4 hrs daily on public transport from the half million flat you were talking about. As I said, hyperbolising weakens your argument. Get your facts right.
I'm not getting into this inter-generational war, fostered by people with an agenda to divide and rule as a distraction from the failure of successive governments to address the housing shortage and social inequality. But anyone with a family, like me, is well aware and directly involved in the problems faced by succeeding generations. I'm also in a better position than someone your age (I'm assuming) to compare them with those faced by mine.
As I said, yes, it's more difficult. It will take longer. And it shouldn't be like this. But, as psychomath has illustrated in her post, Martin Lewis is right in his advice, even for someone whose total take-home pay is the same amount as the journalist's disposable income. She needs to apply the same focus and drive as she has given to her career on saving for her future.
