The article skirts around the most relevant issue: Parasite industry.
How long would it take a farmer to produce $5M in food? What about a skilled tradesman or computer programmer? How long does it really take to "make" the $5M that execs take home every year?
Years of productive effort by real wealth creators in the economy have been sucked up by company executives in financial companies.
You can't have thousands of execs, share traders, etc making $Billions whilst at the same time off-shoring all your industry and putting farmers into poverty.
The financial industry and the super-rich have taxed the economy to it's knees. Ironic now to watch the "small government" Neo-Right scramble to get taxpayer funds to keep the right to make profits. (the Right don't mind government spending, just not on the poor!)
The financial wizardry amounts to creative accounting, which can be attributed to a lack of legal guidelines. Sadly, the only ones who know what laws to introduce are also the ones gaining from the lack of laws.
Once again, the poodles in government are being led by the wolves in big business.

Why does this make me think of Barry Jones and his book on post-industrial economies, clever-country, yada yada yada?

Of course, that's entirely a rhetorical question!

Every great wave of financial rise and fall over the last 1000 years has had two distinct effects.
Over time the waves have crashed from higher heights and more quickly than the one preceding it.
In the aftermath individuals have acquired many more personal freedoms then prior to the crash.
One can only hope that the freedoms gained are at the expense of the corporations that dominate our social landscape.
