After reading through the thread, I came back to your orignal post Orchidflower. The data does seem to support the real money still being concentrated out East. But, of course, for any given individual, that doesn't necessary imply that the most desirable lifestyle is out East!
I guess I'm not seeing the data here, unless you are just counting millionaires as having "real money". For one thing, a million doesn't go very far in a lot of places, especially either coast. In the midwest, with the lower cost of living, especially real estate, it does mean more.
I think of the "real money" more as being held by billionaires and mega millionaries. The billionaire numbers are easier to find. I found a better link to the states count of the richest 400:
The Forbes 400 - Forbes.com and chose the Filter by State pull-down.
California has a lot more than New York. Texas looks to be the clear #3 unless there is a state I'm forgetting to check. Probably Florida and Illinois next. States like Washington and Nevada have 5-6, just like New Jersey, Massachusetts, Virginia and Maryland. The east coast states are smaller and there are more of them so they start to add up, but the population density is a lot higher too.
So looking at it from those 400 people, the big wealth looks to be mostly concentrated in the NYC financial center and Silicon Valley, and then smaller pockets around other areas like LA, Chicago, south Florida, and then somewhat scattered. There are more large cities in the east so there are more of these small pockets there.
I don't really care that much, but it bothers me a bit when someone takes one statistic and draws a much bigger conclusion out of it than it merits. I've just done the same thing with 400 billionaires, so I wouldn't say I've disproved the notion. My point is that another statistic to look at to determine where the "real money" is leads to a very different conclusion. I don't really know which one is right, it really depends on your definition of "real money". I thought in past discussions on this board most people had agreed that $1M isn't rich. I thought we had a poll, but I can't find it with a quick search.
