mixed income is a definite improvement - and Chicago is betting the farm that they can make it work. The untold story - however - is the enormous (10's of millions of dollars per year) federal investment in housing that Chicago is giving up to try and make it work. Thousands of units of project based housing assistance have been converted to tenant based project assistance. That tenant based assistance dies a silent death of attrition - the housing assistance is slowly diminished (through natural attrition) and not replaced. Ten years from now we will look back and see Chicago as the city that said no to federal housing assistance - and will that be a triumph - or a tragedy ?
