Given that you don't seem to understand what a gold sink is, you obviously are not a "fellow millionaire".

Gold Sink - something to spend money on for no great return so that the gold goes out of the economy rather than into a fellow merchants pocket.

So you have ALL the mounts you could buy, ALL the epics you could wear, ALL the vanity items you could acquire. You have 10 toons on the one server all with oodles of cash and all of the above as well. Rather than asking Blizzard to create a gold plated WC with flashing lights and dancing girls for you to go all inception on with your current load of crap you could buy/make/find stuff for a newb. Get them a nice mount when they ding 20, 40, 60 or 70! Buy them an epic axe/sword/staff/shield/mace that you saw on the AH. Heck buy/make/find them every pet they could ever imagine.

Every thing you buy from a vendor, make with farmed mats or find but don't sell for profit and instead gift to someone new will take gold out of circulation. PLUS if you take the CUSTOMER out of the market, no one will buy your stuff and so you won't make any more money and therefore inflation will be slowed. I'm no economist but I'm pretty sure prices only go up when supply can't meet demand.

If you can't do anything about supply try acting on demand instead :)

Gold sinks means destroying gold, not redistributing it.

Unfortunately an alt doesn't need as much gold as you would think. I honestly send my alts 2k, and 4 netherweave bags, and that'll do until level 70. 2k, while noticeable, still isn't that much to a middle-class player with a 5-digit bank account, especially since I really don't have anything to buy.

That's a nice thing to do, but it isn't destroying gold. In fact, it's making the problem worse for other newbies, as your favoured level 10 prices them out of the goods they also need. Leading to... price inflation.
