Any salary increase has to be taken in the round - the complete package of housing, transport, medical, dental, job security, the responsibility, the chance of promotion, the fun, the recognition, the cameraderie, job satisfaction, chance to do AT and representative sport, the challenge, the access to top class gym facilities, and ultimately the feeling that once is doing something worthwhile for others etc when making comparisons
I'll concede dental, but the rest? Nah.
