If you look at the income curve of household income over the last 100 years, you will see that the curve went from clumped around $60k to flattened and rolled out extending up to hundreds of thousands. Put simply, back in the day everyone earned pretty similar pay. Nowadays pay is much more spread out and lots more families make way more money than they would have 40 years ago. The market really loves these high earning households (not billionairs, I mean $100k+) and naturally gravitates towards catering to them. The $60k households get left out.
