Not too sure it really is as close to solving the debate and I'm not sure either of the guys backing Modern Money Theory or Austrian School theory (this link in case anyone wants in) would agree this lays their case(s) to rest!

Interesting read, nevertheless. But there's also a lot of fresh conflicting evidence against the selfish gene (@dothebeats for e.g. more evidence shows we're not as instinctively anti-altruist as we think, as a recent Swedish study of public CCTV footage shows), suggesting that modern generations using modern money might actually not fit the logical mould anymore.
