Over the years history has shown that when a government needs money they will find a way to get it.

FDR confiscated all the physical gold in 1933.

The US recently proposed an 8% mining tax on all new US mines.

The US is currently proposing a winfall tax on the oil Companies.

Canada changed the taxation rules on income trusts.

In the end there is no really safe place to hide the rules can be changed at anytime.

My philosophy is just to make the best decision with the current rules that I can and hope in the end that they leave me some crumbs.
