Bishop,
For the sake of discssion use
$100,000CDN to compare salaries. (With our recent contract, this is app. what you'll make in Canada after being in the TMA for 11 years.) This salary puts you in the 54% tax bracket.
You don't really mean that an 11 year TMA controller in OZ earns $50,000/year do you?
