Apple takes 30% of app store purchases, in-app purchases, and iAd revenue. Google takes 30% of Google Play purchases and in-app products. 30% is a reasonable share for the maintainer of a network to take.

As for the 25% to the author of the mod, that does seem unfair, but I don't think that was Valve's decision. I think they left that up to the game producer, Bethesda in this case. Bethesda chose how to split the remaining 70%.

As an aside, Valve's income per employee is totally irrelevant. Their 30% fee is set by market forces. If they lost billions of dollars this year or if they hired 10,000 people to handle support calls, the "fairness" of a 30% fee is not affected. It wouldn't become more fair just because their income per employee ratio changed.

That 30% is set by market forces. It's what we've all generally agreed a marketplace can charge for operating the infrastructure. In this case, Valve has a challenge, because there are multiple parties splitting the remaining 70%. So they might need to lower their fee to let the game producers and the modders take larger slices of the pie.

> while the government is _much_ more important than Valve is for any business.

Hah. If only that were true. The government's only positive role in commerce is ensuring political stability. Lots of times, they fail hard at that one job.

Once you have political stability, then the government becomes a power broker. The tax system is really an elaborate financial instrument for big business, has been ever since the dawn of mercantilism. The value you gain from the government is proportional to how close you are to the giant sums of money being funneled through it.

Sure, there are things like welfare programs that ensure an adequate baseline of minimum prosperity, (i.e. the homeless in the US won't starve to death, and might get a bed to sleep on a couple times a week) but you only really benefit from them if you really need them, and relying on them is no fun. And we only have those because those of us close to the poor, who can't just shut them out, threw enough of a fit to force the elites to.

The rest of us, lower and middle classes, small and medium businesses, including entities like Valve, don't get squat from the government. We have to earn our own keep, we can't rely on the government to bail us out.

The government is entirely too small to help out the rest of society in any meaningful way. They can try to pass laws, but laws breed loopholes and suck for the same reason Valve's lofty initiative failed, it's impossible to consider the incentive structure of the new world you're creating with a law until you actually enact it and see what's going on, and there's only so far hiring experts will get you. Legislation is a long, slow slog towards a saner world on the aggregate, and a vehicle for pork in the particular.

The only thing worthwhile the government provides US businesses is in just being there. Great that we have one, but extremely hard to point out specific things it does that aren't already being far better done by other commercial entities.
