Talking of healthcare, the US plan should become a lot cheaper if this trend continues: placebos are becoming more effective. On current trends placebo should be more effective than all current drugs by 2011; by 2013 sugar pills will overtake some common forms of surgery and in 2016, it should no longer be necessary to use Band-Aids or brush your teeth. Fortunately the US does still have some indirect price supports on sugar, or else the pharmaceutical companies would have no way to make profits at all.
