This is just comically wrong, I'm sorry. The grand exchange is literally one of the closest implementations of an in-game item exchange that I've seen that's similar to an actual stock exchange. It's a double sided market using a price-time order book. It's basically a dark pool. Jagex literally took one of the cornerstones of modern capitalism and copied it into their game for their commodities/item exchange.

The only thing that seems even vaguely authoritarian (which is what I assume you mean by socialist, even though that's basically the opposite of the words meaning) was during the no-free-trade thing after their payment processor almost kicked them off due to chargebacks from botters using stolen credit cards to buy membership.

If anything, the original state of W2 was a lot more socialist than the GE is.
