I still think these numbers are too low, at least for my metro area. $60k post-tax in the Philly metro area isn't enough to rent a decent place alone and also save for retirement. Maybe when they say "take-home" they're assuming that number is after paycheck deductions for healthcare and 401k, but they should definitely specify that.
These numbers do not seem realistic 'comfort' wages, and complete fantasy if you have a family.
