Well, you can change the years on the site - if you change it to 2008 like your site, the numbers are fairly close. Your site says 711 B's and the one I listed shows 730 B's. Still, the percentage is no where near 60%, more like 24%.
I think the big picture is really the health, pensions and welfare amounts. That's closer to your 60% and that was before Obamacare...
Bill.
