Somehow over the last 10/20 years, the notion of "rich" has had a much bigger inflation than the rest of the world, this is particularly true in the US. If your definition of "rich" is not needing a paycheck, then 2M with 2% interests over inflation should be enough to live OK in most countries except maybe Switzerland, Denmark or Norway.
OK... I have two answers to that. First, when you are rich, it is easier to get a better return on investment. Because you can afford better advisors, and because you work with higher volumes, bringing the transaction costs down, and possibly accessing to expensive investment products other can't afford. There are many articles on the rich getting richer, I will not post another one here.
Then, second point... Let's say you just get the return as high as the inflation... You still have a 2M pie you can eat from :) That would mean for example 50000$ a year during 40 years, augmenting pair with the inflation. I don't know well in other countries, but for me that would be enough to let the state retirement come. That wouldn't be the millionaire life but quite enough to enjoy my life with what I'd like to do. But for now I rather work and code/design things that matters :)
"when you are rich, it is easier to get a better return on investment" <-- This argument is valid at a scale two orders of magnitude higher than what I am talking about. It's easy to lop people with 1M net worth in the same bucket as people with 10B net worth, but there's a very meaningful difference there (beyond whether or not you decide to get a third bugatti). A million-dollar portfolio is below the thresholds that many financial institutions would consider for an investment.
"Let's say you just get the return as high as the inflation... You still have a 2M pie you can eat from :)" <-- lets say you are 25 now and you live to be 80. Even if you can just match inflation, you have less than 40K per year to play with. In most suburbs of NYC, its hard to live on that (taxes on a house alone will eat away a quarter of that).
Your arguments would be valid if I decided to move to a third world country. I could go to India and live like a king for the rest of my life on less than 300K USD. But now you are comparing apples to oranges here: taking earnings from a place where earnings and costs are high, and exporting them to a place where costs are low.
NOTE: My goal isn't to pick a fight. You will understand when you get there that a million dollars just isn't that much (and not in a keeping-with-the-joneses sense)
I quite get you're arent't picking up a fight :) I understand your points and agree we are picking different environments for investment. As I said, in Europe when you get at 0 when your are 67 (max!) is then covered by state retirement.
Your point made me think about geo difference BTW. It is now clear to me how much the US needs more performance from you to ensure retirement. BTW feel free to tell me if you want to follow that thread per email... I'd be glad to.
If you take an absolute measure of rich and compare cost of living, 250K is really not that much. Especially after taxes and the ilk.
