Some very good comments here. What I am noticing is that those who are planning to vote against the HST are either doing so as a protest vote against the Liberals or they are unable to explain why they believe that the PST is a better tax than the HST.
It has been said by others but I think it needs to be repeated: if you want to punish the Liberals, the proper way to do that is in the next election which is likely not far off. How one votes on the HST referendum should be based on the merits of the tax. If you are not willing to to the research or if you are unable to keep your emotions in check and make a reasonable analysis then you should stay at home on referendum day. This is not a game, it is serious business that will impact the economy and government finances for years to come.
A few reasons on why the HST is superior to the PST:
Fairness - We all know we need tax revenue to fund government services. That said, if we are going to impose tax, shouldn't it apply to everyone and everything in the most equal manner possible? The PST has numerous special rules and exemptions, whereas the HST, though not perfect, is more consistently applied with fewer exemptions. This is a good thing for several reasons. First, it makes it easier for businesses to comply with the tax. Speaking from experience, the PST is the most convoluted, inconsistent tax out there. Second, if special exemptions are on the table, then every industry group out there is going to spend time and resources trying to obtain such an exemption for their particular group. This is a waste of valuable resources that could be spent in other productive areas of the economy. Third, it fosters corruption because the exemptions become a political football that government officials now have something of value to hand out at their discretion.
Economic efficiency - All taxes impact the economy in a negative way but not all taxes are equal in this regard. "Value added" taxes such as the HST are less damaging to the economy than standard sales taxes like the PST, which is why no jurisdiction has implemented a PST type tax in decades.
Administration costs - Since there is already a federal GST complete with bureaucracy, auditors etc., duplicating this entire structure at the provincial level creates additional costs that can be avoided by harmonizing with the GST.
Impact on individuals - Even before the government proposed reducing the rate by 2%, the majority of British Columbians particularly those of low income were going to be better off under the HST after taking into account the expanded HST credit. With the 2% rate reduction virtually all British Columbians will be better off.
