I agree, I don't think it's the panacea for that problem.  It's a start though.  The toughest things to get over imo, are the meme's that people will never use math and/or that math is not useful in the real world.  The KhanAcademy handles the problem of insecurity about math and a gentler introduction to the topics once someone is interested enough to consider learning it.  How you instill that initial desire and overcome their deep seated biases and insecurities about it are a much harder problem.
