If houses prices didn't go up so sharply then buying a nicer house for more money would mean the gap in price would be smaller and achievable, it's all relative to wages too not just the gain in house price as you have to plug the gap with more debt, yes we are going round in circles because you won't accept that with the 50% rise an increase in this house of 60K means that anything better increases by more than that so the difference just becomes a bigger mortgage than I already have.
I completely accept this when looked at in dollars/pounds. (It's just straightforward math.) When looked at as a ratio of incomes, indexed to inflation, etc, it's not as large as the nominal increase.
Yes ultimately it comes down to wages, that is why people are stuck renting from ever larger landlords than control the market being able to buy houses cash and charge huge rents preventing them from saving for a deposit while your local MP uses his wife's name to buy a second home via a scheme that gets him a zero interest loan and was meant for first time buyers not politicians playing the system.
Presumably if the people care enough, they can vote such MPs out when things like this are discovered (or prosecute them for fraud if the elements of fraud are present and provable)?
I look at the wages issue as a relative issue. If your wages are rising/falling at the same relative rate as everyone else with whom you would be competing for housing (whether bought or leased), you're neither getting ahead nor falling behind. If your wages are rising faster, even slightly faster, you're making headway against them and improving your [financial] station in life.
It means that when house, car, milk, or eggs prices go up by N% for everyone, your income has gone up by (N+1)% and you're able to save the difference. Conversely, if your wages are trailing, even slightly, the average among your peer group, when prices go up by N% and your income only by (N-1)%, things get a lot tighter for you over time.
Compounding interest is a long lever. If you're on the good side of it, it's awesome. If you're on the bad side, it pinches your fingers like hell.
