Part of the problem is that none of the parties address the real problems created by their actions. Liberal introduce a nation-wide carbon tax that should in theory tax large companies. In reality: Companies don't pay taxes, they raise their prices to cover the tax increase which "trickles down" (the only time trickle down economics actually "works") to the people.
So without dealing with that scenario when implementing the taxes, the ordinary Canadian gets hosed.
But now lets say PP becomes prime minister and reduces the taxes. Is he going to force companies to drop their prices to make up for that? Probably not. Companies will just use that as profit. So Canadians are still getting hosed.
And now after that lets say Liberals rise to power again. And re-implement these taxes. Once again, the companies will just pass those added costs onto the consumer again.
I wish I knew what the solution is here but I really don't. It feels like no matter what the government in charge does, companies just keep using it as an excuse to hose us one way or the other.
