In the aggregate level, only 56 percent of all personal income comes from wages and salaries, with the rest flowing from other sources, such as investments, rent, Social Security and private retirement plans.

Add living off the rising home equity and the wages might be below 50%.

The bean counters like to say rising home value is only an increase of wealth and it really isn't income (!?).   Of course, even without home equity, people's wages are not even 2/3 of total average personal income.

Then again, for people like you and me who live on the Planet Earth, any increase in wealth is income -- so IMHO what you posted was absolutely right.
