There are other values than being business-friendly, and claiming the NDP is not business-friendly is not really accurate anyway, they're just not as friendly to business as the jurisdiction to the west is. They're a little more interested in things like occupational health and safety, decent wages and living and working conditions, stuff like that, all things that cost businesses money.
Interesting that you mentioned highways, it's a nice example of what I think is wrong with your kind of thinking. Do you really understand why so many of the secondary highways are in the shape they're in? It's because of the kind of people you'd vote for. Saskatchewan used to maintain its own highways directly, the Department of Highways had its own work crews and heavy equipment and I'm old enough to remember when they took care of things pretty well. The Devine government gutted the Department, on the theory that the private sector could do a better job of things, and sold off all the equipment to its contractor friends at ridiculously low prices. At the same time, there was a right wing federal government interested in "rationalizing" the grain handling and transportation system, which ultimately resulted in the closure of many rural elevators and rail lines. That meant grain producers had to truck their products much longer distances to fewer, larger, more centralized collection points. The result: heavy truck traffic on roads not designed for it, and that eventually broke up the road surfaces pretty badly, but by then the government had changed. And the privatization of road maintenance made it so expensive that the volume of work being done fell off significantly, so the highways decayed. The current government is being blamed for it, and while I'd immediately agree it should have done something about it long ago, things aren't as simple as you'd like to think they are.
I'm not defending the current NDP administration in Saskatchewan, I'm no leftist, I'm not generally a fan of paternalistic governments, and I'd also agree with your implicit claim that the NDP has been in power too long, it's time for a change. But I'm no fan of the political right in its current incarnations either; conservatism--I mean *real* conservatism, principled ethical conservatism in the style of Robert Stanfield and Dalton Camp--doesn't seem to exist in this country anymore.
All the options suck. I have no idea how I'm going to vote, they all give me the willies.
