There are a lot of posts on here that focus on two very suspect ideas. 

The first is that the BCLibs have provided the lowest tax rate in Canada. Having a low income tax rate is meaningless if there are high fees for services. Medical MSP by far the highest in Canada. ICBC rates rise while the Libs take "profits" to replace taxes they told us they did not need. BCHydro as well. Rising ferry costs that have shuttered almost every island business. Tolls on bridges that people must cross to get to work. These fees are just another form of taxation, a regressive one that targets the have-nots in society. 

The second is that earning $150k year does not mean you should pay a higher tax rate. If you are in the top 2% of earners you may not be rich - but you are doing better than the other 98%. We already have tax brackets - if you earn 35k you pay a lower rate than those who earn 75k. So why not have one or more brackets for higher earnings and get rid of fees and shadow taxes on services.
