Wealth =/= spending, and definitely doesn't equal consumption.

Elon Musk might have more wealth than 1,000,000 US households, but he doesnt eat 3 million meals a day, drive a million cars, or sleep in a million houses.

I would be very interested in seeing the breakdown of consumption instead of wealth, as competition for goods and services produced is where disparity has tangible impact.

However, the productivity of workers in relation to capital is a valid concern for their ability claim the goods produced.
