But in my dad's day, a young couple with only one person earning and the other a sahm could afford to buy a massive five bedroom house!
Yes, and we are not in those times - and life was bloody awful in almost every other respect. To have this situation, most women would have to accept they have no chance to work - so that household income reflected that. You can't just choose to have one part of it - it's all tied in. House prices will always match to the lifestyle of the day.
I'd love to blame Tony Blair for pushing so many people to be graduates - but to be fair its a global theme.
It is completely unsustainable for non-graduate jobs to pay so little that people can't be in the community as a whole. The only answer is to move out so these jobs are not done, and then the wages will rise in the local area - the issue in many cases is national pay scales that need to be scrapped, and local ones put in place.
However two people on NMW will earn around £30k per year, giving £2,300 per month. Again, on the same basis this will leave £700 pcm, so after 4-5 years will have a similar ability.
It really is about making these sacrifices and cutting your cloth accordingly. If the NMW couple lived a little away and even bought a £300 car then may be able to save £900 per month - but taking a ham sandwich to work for 4 years for lunch may not be a sacrifice people are willing to make. Making the choice to have children will make it very unlikely for many in today's world - but it';s a choice.
If your single and don't have friends to share/buy with - yes, your screwed!
