Tax Creep
Roger,
here in Canada houses used as a principle residence have no tax applied at all at time of sale, the gains are for all intents and purposes fully tax free, it's one of the extremely rare examples where the Canadian tax implications of assessing a given asset's gains are more favorable than the US equivalent.
However as it applies to houses in the US if you are "buying up" after your principal resident house sale, and do so within a specified time, you pay no tax in the US also. And if you are "buying down" you only pay tax on the differential net gains.
In almost all other circumstances, from interest rates, to costs for basic goods and services, to capital gains, to interest income, to business deductions, to wills and estates, to retirement implications, etc the US presents a much more favorable environment than does Canada.
