It's a standard, in corporations—but they mine it better.
What happens is that as the years go by and the tax-free savings accounts get more and more money in them, given the distribution of income in this country.... First of all, it does nothing for low-income people; second, it means that this income is going to increasingly treat all investment income as tax free; and third, it will be splitting the investment income with other family members to get that tax exemption.
It's really the perfect complement to pension income splitting. I gave you some tables last year showing that people with $75,000 or $80,000 worth of income could get $8,000 to $10,000 worth of tax refunds from income splitting. Now they can just take that tax refund and dump it into a couple of tax-free savings accounts.
I guarantee you that within 20 years high-income people in Canada will not have to pay any taxes.
