That's certainly the challenge, because I don't know how the GST rebate as currently structured, that comes to people on a quarterly basis, is necessarily going to address the inequities in income if you have to wait every quarter to get the money to pay the additional taxes you might be paying on your consumption. That's a bit of an economic hardship, and there is a challenge in identifying a better way of targeting some equalization strategies for the economically disadvantaged.
Similarly, if we were to go to a concept of an ecological cost of ownership tax, there would also be an issue of how to develop strategies to lessen the burden on economically sensitive businesses.
