In my country, politicians regularly act in the interests of demographics with high voter turn-out, and against the interests of demographics that can't vote or have low voter turn-out. Given the choice of cutting benefits to retired people or cutting benefits to young people, the young people will get the cut much more often.

It'd be great for /me/ if only people with a masters degree or higher could vote, as the government wouldn't have to waste time addressing the demands of 95% of the population and could instead spend more resources on people like me.

I don't think it'd be good for 95% of the population though.
