People desire to own their home, I only speak as an Australian and in Australia house prices have reached levels, that saving anywhere from $30,000 to $50,000 for a 10% deposit or $60,000 to $100,000 for a 20% deposit is just impossible. If Australian had mortgage regulations like the US, there would be a massive real estate crisis by now, because so many people would have taken out sub-prime mortgages.
