I suspect that there are 3 classes of people when talking about employee benefit costs (in a employee vs contractor discussion):
1) Private sector, high pay professional - I would agree benefits could be around 40%, but this also only applies to maybe top 20% of non government employee population.
2) Government employees, maybe even more than 40% considering their post employment benefits.
3) The bottom 80% of non government employees, who I doubt approach anywhere close to a benefit value equal to 40% of their pay.
