Business Insider has a page that features a ton of different charts and graphs on wealth inequality. It would work great in conjunction with an activity on Occupy Wall Street. The graphs start off showing how unemployment is at an all-time high (since 1940), then they look at CEO pay and corporate profits.
The graph I have included here compares corporate profits and CEO pay rates to production worker income and minimum wage. It makes a clear statement against the argument that a rising tide lifts all ships. Corporate profits and CEO pay have risen tremendously since 1990, but the trickle down of jobs and middle class income has not materialized.
Another interesting chart (far down the page) is one that compares wealth inequality in the US to that of other countries. We currently rank 93rd, behind China, Iran and Russia. Even further down is some information about how banks are using the money they are borrowing from the government at virtually 0% interest to buy treasury bills, profiting from free loans with zero risk.
These charts could be used in a wide array of activities on business, wealth and poverty, globalization, and worker’s rights. The page as a whole is probably too much, but a few carefully chosen graphs or charts would make a great addition to a reading or discussion activity.
