And yet many countries with PR still have crap governments and bad policies. You’ll never have a perfect system since you’re still expected to choose one party, but there’s a large number of policies and issues to address, and the odds are that no party gets the mix correct for most voters. It’s a one-dimensional system to implement multidimensional politics. So quibbling over the particular metric to use to allocate seats along that single dimension is missing the larger problem. Something closer to direct democracy might be better, but that requires an engaged, disciplined and educated electorate.
