RE:US/Canada Union - similar to EUthanks for the comments, I forgot about drug dealers and guns in the US. With that said thou Canada system for punishment for crimes is an absolute joke. We also need tougher penalties for tax evasion here as well like the USA. Far too many people in Canada working under the table and Canada's current socialist system and high taxes really precludes people from working or paying taxes/working above the table.
Not sure I agree that it would kill the real estate market, there are a lot of expensive areas and cheap areas in the US just like there is in Canada.
I do like the idea of a common currency, I am fed up with the ever fluctuating CAD/USD and its in the toilet. With everything we buy ultimately purchased in USD on the world market, I can see inflation kicking up again.
