Canada also have the "investor program (not passport, thanks robteix)". (grants permanent residency visa)

It requires you to be accepted through an application (no criminal / health problems) and to 800k loan interest-free to the government for 5 years. You also need business experience and at least 1,6m$ in legally-acquired assets.

Maybe Australia also have other criteria ? I think countries on that list don't ask many questions...

Pretty bad "article" overall. It could've offered so much more information :(
