@kev I lived this way for about seven years, while working in IT for a large bank. At the time, I thought the pay justified the near complete lack of a non-work life.
When the recession came along, myself and more than half the IT department were shit-canned, outright fired under a new policy specially implemented for downsizing.
I now work in the non-profit sector, for dramatically less pay, but I love my job, and I'm much happier in general.
Fuck corporate culture.
