Why does Saskatchewan have income tax?

No, seriously, why? A philosophical question.

I'm not from Saskatchewan and likely will never be in Saskatchewan, but I'm moving my business (in IT) from BC (where Liberals & NDP are trying to push all business except for oligopolies away from Canada) to Texas, and this got me wondering.

Why don't we have a business-friendly province (like Texas or Florida) in Canada?

Saskatchewan currently has only about 1 million in population. If it had a tax treatment like Texas, I'd gladly move to Saskatchewan with my business and create jobs there. It could be the next Texas of Canada, with economic prosperity but without guns.

EDIT: are all people in Saskatchewan this rude or is it just this sub? I just wanted to get an honest opinion but got a whole bunch of insults and "don't come here". Mods can lock this post, I guess this is my first and last experience with Saskatchewan. I'm not deleting it so that people can have an opportunity to reflect on their behavior.
