Hi Professor Wolff, In your most Economic Update, Housing Crisis US, you mention that the standard of living for the bottom half of Americans has stagnated or dropped over the past 40 years. Do you mind providing a few links that reflect this data? Thanks a ton.
Rather than provide the "few links" that you request, let me go one better and provide you with the link to which most researchers go to get the best facts and figures on income and wealth inequality. The economists Thomas Piketty, Emanuel Saez, and Gabriel Zucman operate a growing research team - much of it based at the University of California - Berkeley - that you can follow via this link: https://eml.berkeley.edu/~saez/ACPSZ2017AEAPP.pdf All their work is available free to everyone interested.
