Is The CTA Unsustainable?
"The CTA is not exactly running out of money ... but it is on its way to running out of passengers. Over the past 20 years, the CTA has lost more than one-quarter of its ridership. As a result, the public subsidy per rider has risen at least 20 percent, after adjustment for inflation. If the CTA had kept its subsidy per passenger within inflation, it would be spending approximately $100 million less per year today."
