Don't bull la... you're saying a non-medical manager earns equal/ more that a Registrar? Usually non-medical grad goes in as Executive, then Senior Executive, then Assistant Manager and Manager. Manager usually takes about 6 - 8 years to reach. Some take 10 years even. Granted that starting salary is about $3.2k now, you think it can triple in 6 - 8 years time?

The more reasonable range to think is around $6k - $7k. So please don't mislead people.
