When high school graduates go off to college, they are making strides towards a brighter future not only for themselves, but for their communities. If a city steps up and offers to pay college tuition to students, that will encourage more people to attend college, and the impact on the community will be greater.
The "Kalamazoo Promise" is a good social and economic model for cities because it creates economic development. Additionally, for students who use the program and plan to stay in the area of Kalamazoo, a better workforce will exist. Socially, the promise helps encourage high school students to strive for higher grade point averages and assists them with college.
