What is doubly ironic is that are income tax load (at least in BC) is identical to california before health insurance costs in california. If you add health insurance it's even more. And in BC tech companies get a lot of tax deductions, especially small businesses. The sales tax is about %4 higher, gas is about %25 higher, car insurance is more expensive-ish, food is a little bit more expensive and the shopping isn't as cheap. But that's all dwarfed by the health insurance costs in the US.
Which is odd. Given the social web that we have supporting us in Canada you would expect a much more vibrant entrepreneurial spirit.
Maybe the mindset that lauds and supports this type of support is one that is not willing to take the risks in the first place (at least, not in the same numbers).
