Michigan\'s community colleges should hold the line on annual tuition hikes. The schools are the best hope for students looking for affordable college classes. This year, the state\'s four-year universities refused to cut budgets enough to keep tuition hikes low. They hit students with increases of up to 19 percent, nearly six times the rate of inflation. As a group, university presidents decided to push the hikes, take the heat and then go ahead and force students to come up with the extra money this fall. The state\'s education safety net is wobbly, with universities blaming high tuition on uncertain state funding. Either way, many students are reeling. At Wayne State University , for example, students are primarily commuters; most hold down jobs out of necessity and more than a third are minorities. The school meets these conditions with cheaper tuition. But the school\'s urban role has been jeopardized by Wayne \'s 18.5 percent tuition hike, amid reported plans to raise tuition substantially higher over four years.
