These companies colluded to depress the wages of an entire industry. "50,000" people were not effected. "64,000" people were not effected. Those numbers are just the work forces of the companies involved in the lawsuit.
The entire greater Bay area technology job sector, one of the highest paid jobs in America, in the region of its highest concentration, was artificially depressed. These companies put a ceiling on what a given job was worth. If you work in Silicon valley in technology, you were effected. The ability to moved to another company and get paid what you are worth was effected.
The shear scope and damage these companies did is almost beyond belief. We are not talking hundreds of millions of dollars. We are talking Billions and Billions.
The ripple effects are even crazier. How many new technology companies did not get created because people's depressed salaries reduced how much they could save to bootstrap something new? How much did technology workers not spend into the service industry or the larger economy, because they were underpaid?
This is a staggeringly insidious act with wide reaching repercussions beyond Adobe poaching some PhDs from Google, or vice versa.
