Should I be ashamed? Efficiency pays. Harmonization streamlines the administration of the tax, and is more efficient than a straight sales tax, as it allows businesses to get credit for the tax they pay on inputs (as a deduction off the tax they collect). Exporters can reduce their prices by the amount of the tax they pay in imports that previously would have to be covered in the price. I would probably prefer a broader tax (i.e. with fewer exemptions) at a lower rate and more targetted help for low-income consumers. But, in principle,
I am not opposed to the HST.
Consider this startling passage from the Mintz Report. It suggests that 82% of the increase in capital stock and 80% of the job creation resulting from proposed changes to BC's tax regime will result from sales tax harmonization--i.e. only 18% and 20% from corporate tax cuts. Thus, if one is really concerned about the equity of shifting tax burdens onto ordinary consumers, I suggest ditching the corporate tax cuts, not the sales tax harmonization.
