That shows 50th percentile disposable income shooting upwards over the last 20 years and the only competition being Norway and Switzerland, and breaking away upwards from the developed country average. Again, if OP is waiting for prosperity and doesn't see it yet, they'll be waiting forever. Add US, Germany, France, Spain, UK and you'll see the US graph incomes shoot upwards for 10th, 50th, and 90th percentile, and the other countries stagnate or even decline, even for the 50th and 10th!
