Who is they?

The same government that destroyed us over the past decade. The Liberals. AKA globalists.

How would it better?

I mean, the billions upon billions that we pay to Quebec for 'equalization' would be a start. Those funds stay here. Better health care, better jobs, better quality of life. I don't know how it would be better to stay in this abusive relationship we've endured for decades.

First nations people...

Nah, the first nations chiefs have made it known because they get lots of cash for being good obedient servants of the government. Talk to an every day native citizen, they will tell you a different story.
-> We don't need the east...

Tell me what you offer us? Seriously, no disrespect, what does the east offer Western Canada?

I worship God the Creator of all. Way too much sin on this planet for it to last. This earth will be destroyed anyways and re-made too, Revelation is awesome, a must read ;)
