But that's my point, employers are giving it (kinda, I'll circle-back to this). The full-time offer has gone up $9k in the last 12 months. Contrasted with the ask that has only gone up $6k in that same time-frame.
Now, is $70k a livable wage? Hard to say without a more specific location. In bumfuck Alabama, probably. In LA, hell no.
The calculator defaults to semi-monthly and I think the original commenter didn't change it. Also, it defaults to your current location so the take-home will be different for everyone running the calculator (because taxes). $78k is $6500 a month BEFORE TAXES.
