According to this infographic from Denver bikes, four of five dollars you spend on your car leave your local economy.  To keep 130k transportation dollars in your local economy your city would need to reduce car ownership by 15k cars.  Which could mean 15k more bike owners, and bike money stays 100 percent local which makes good business sense.

By this logic, imagine if everyone stopped shopping at big boxes, eating at chain restaurants, bought at local druggists instead of at Duane Reade and RiteAid, stopped buying iPhones and iPads.  We would have a much better economy, with much more vibrancy and choice and local control.
