How to benefit from petrodollar recycling

The massive amounts of money being made in the Middle East will eventually(at least some of it) make its way back to the West These guys won't be buying Rockefeller center like the Japanese did or other trophy properties. So what are they going to buy? How can you benefit? Unlike the massive petrodollar recycling of the 70s and 80s, it won't end up in Treasuries. Some of it will be in gold. As we've recently scene, some of it will go into private equity firms and the exchanges. Alot of wealthy Arabs have been investing in the U.K. For there purposes, it's seen as a much more tolerant place than the United States. This is part of the reason that London real estate is some of the most expensive on earth.
I think that you should take a look at luxury manufacturers, which will also be getting tailwinds from the rise of rich Asians. The easiest way to do this is buy buying the Claymore/Robb Report Global Luxury Trade Index ETF(ROB). The index is made up of financial services companies, upscale retailers, hoteliers, resorts, and other companies that cater to the wealthy.
The company in this index that I like best is Embraer(ERJ). Embraer makes commercial jets, private jets, and has a defense segment.
