I have nothing better to do on a Saturday morning than go over finances. In doing so, I realized that I had miscalculated the tax incidence graphs I had previously created. The biggest change is for payroll taxes in college: instead of looking at my W2s I just assumed I was paying full Social Security and Medicare taxes on my student jobs. In fact, I was not. This reduced my tax burden in the late 90s. The 2012 blog post has been updated with the most accurate figures.
