Notice that young couples today have a greater income, in relative terms, than we did at the same age with the notable exception that a much greater share of their take home pay now goes towards mortgages. Major cities in the world are seeing an inflation of pricing due to to speculators to benefit people who sometimes do not even live there but want a foothold for future use. In some areas they have ostensibly created ghost buildings.
Part of our global effort to fight increasing income disparity must be focused in this area to keep communities viable and healthy. The alternative is to see a worsening situation where housing for future generations becomes a hazardous enterprise to undertake because it will impoverish many of them while the top 1% continues to drive up pricing.
