It's a biased question meant to lead the person taking the test to say yes. So no.
Political Compass has a ton of these, from the left and right, for a good reason. It gets them to know how far left or right the person really is. Instead of just asking a bunch of different propositions and agree or disagree (Atlas's Matrix), they add a little ideological purity/hackishness in there to see if you'd really go that far. I think its actually a good idea, my PC score usually looks more moderate than my PM score.
Maybe. I can see you point. On the other hand though, the question is flawed (firms don't have to be 'predatory, to end up as monopolies, and why specifically multinationals), as well as biased, which isn't surprising, given that its known to be biased in a centre-left wing direction (I think it has some association with Neil Kinnock). I mean, if the test was to work in the way you suggested, it would be better to come up with a set of statements ranging between the extremes, as opposed to one statement which your supposed to rate how much you agree with it.
I find the PC website extremely odd. I find the questions skew you to the bottom left, while the analysis of major parties is absurdly skewed to the upper right quadrant.
They seem to subscribe to the banal "all parties are the same everywhere" ideology that's all the range in some fringe circles. I'd be surprised if Kinnock, of all people, would be involved with that.
