Over the last 30 years mortgage rates have decreased and with that savings rates (the less it costs to lend money, the less you pay to purchase money). An emphasis was placed on creating wealth in home equity and the stock market vs. saving from your job/paycheck, and living off interest in retirement. Unfortunately it's hard to turn things around (deflation causes depressions) and we have to accept that it's going to take time. Our generation will never see the increase in home prices the way our parents and their parents experienced. The same goes with the stock market. We're overextended and it will take time for things to even out.
Being rich is having the amount of money that allows you to live the life you wish to lead. It's going to be more difficult for our generation to reach that point, but you can never go wrong with saving and preparing for retirement.
