While I agree with your assessment of the dollar, the Euro still has some major flaws that make it more dangerous. Many of the countries (Greece, Spain, Portugal) attached to it have too many entitlements that cause the government to 50% or more of the country's GDP and it spends more then it takes in. The banks that are responsible for givin' out too much money are interconnected with banks all across Europe. If a country like Greece, despite a GDP comparable to that of Dallas, Texas, fails the entire currency runs into issues because each individual country cannot print off more money.
Though, I am very concerned that a similar event may unfold with California and Illinois. They have run record deficits and are not even apologetic about it.
I would agree that Capitalism has some flaws, but that certainly does not make it a failure. The rise in the financial sector does have its benefits, companies that accomplish breakthroughs in technology are able to receive funding at faster rates so they can invest more in their products. Granted, it opens up the possibility of crashes if a bubble is formed, but allowin' for successful businesses to expand is beneficial for many people. I have not read the book, but as a rule I make a point to stay away from anything Marx related.
Japan's stagflation was not caused by capitalism but rather excess amounts of Keynesian economics.
I agree about Japan, in fact, the US has been headed that way, thanks to the Fed, which actually brings me to the Euro and how it has it's own central banking agency that is responsible for printing coins and notes, and while Greece may have a crappy economy and be quite spendthrift they do not have the ability to print as much as they like, so their damage to the Euro is actually pretty limited, especially given how small their economy is compared to the other members. No doubt bad apples like Greece might affect investment in the Euro but really it would create a buyer's haven on fears of Greek economic collapse. What about Ireland? Their insolvency didn't seem to much affect the pound and Euro. The reason the US dollar is on a trainwreck long before the Euro is firstly the Euro is getting increased investment, China is selling off it's US notes for more tangible assets or even Euros. Dollar value is greatly diminishing, plus the Fed has outright declared it wants to keep printing like crazy, further devaluing the dollar. The only reason the dollar was ever strong was because of past exports, and worldwide implementation of dollar as a trade currency, along with the gold standard. Soon as the gold standard was ditched, soon as the artificial inflation began just pre-dotcom boom, soon as more countries move away from the dollar, the more unstable the dollar becomes. It's quite a trend that since the dotcom boom and after the dollar has sunk significantly. Both Schiff and Ferguson point out that overseas is, unfortunately, the best investments, especially for long term, as it's very very unclear what shape the dollar will be in 10 years down the road. The Euro will rebound, and countries like Greece can always go back to their own currency.
I will agree with Tosh and for the very same reason you did about long run capitalism not working but that is indeed because of Keynesian economics on steroids. I don't think the dollar would be in as bad of shape had there been no artificial inflation of prices, reckless amount of printing, and government taking over bad debt. However, the dollar decline and the high amount of US debt needs to have someone banking off of it, and well, ironically, it's China. Perhaps the RMB is a better long term investment given the path to restrained inflation they are headed.
I gotta say though I like the fact that I'm discussing with some fine chaps who actually know what they're talking about. It's really soured me on any subject concerning the dollar with the Captain America attitude and how brilliant guys like Schiff get the flag in the face for being more forthcoming about the dollar and US investments.
