Former U.S. House Speaker Newt Gingrich has outlined his strategy to combat rising healthcare costs, a plan that includes insurance mandates for people who earn more than $75,000 a year. Gingrich called it "fundamentally immoral" for a person who can afford insurance to save money by going without, then show up at an emergency room and demand free care. Under Gingrich's strategy, those who can afford insurance and choose not to buy it would be required to post bonds to pay for care they may someday need.
