You'll note, unless you are a wildly optimistic estate agent, that pay is increasing more slowly than house prices.
It is taking people of all ages longer to save for a house on average, in the UK as a whole (the rate of house price increases is outpacing pay increases by 11 per cent since 2005), especially in London (65 per cent).
This doesn't take into account the fact that the young are underpaid.
In addition, since 2005, young people have seen relatively meagre raises in pay when compared to older workers:
Our cost of living (likely to increase due to a Brexit we didn't vote for) is getting far more expensive, while pay remains stagnant.
In short, saving on the occasional Pret sandwich isn't exactly a solution to 'Generation Rent', is it?
