Can absence of inflation be accounted for by a reconfigured class structure? A previous and oft-heard question asked why no inflation results from the Fed pumping money into the economy.

Are we simply seeing a methodical wage suppression, thus no official "inflation," while prices soar in certain sectors dominated by "shareholders," non-wage income, and the "one-percent" or whomever? 

The money moves first into the financial industry, where actual production investment is less attractive. It seems that as long as no money gets locked into "sticky" labor contracts, the Fed can pump away and the results are not deemed "inflation." The money does not cycle up in wages or wage-earner goods.

In other areas, however, we do see soaring prices: art, luxury goods, high-end urban real estate, philanthropic gestures, political campaign funding, ivy educations, high-tech medicine, hedge fund fees, dividend payouts, tax-avoidance cash hoards, stock bubbles, etc.

Can the absence of official "inflation" be explained in large part by the "disaggregation" of labor, middle-class debt, and a new class configuration since the late 1970s? More like a "redistribution" or even a "customizing" of inflation.
Quantitative easing without high inflation can be explained by low velocity of money.

Think about a property tycoon who sees times are hard and instead of investing all his money in a development project, he buys gold which he keeps in a vault. The property project would have provided employment, and the wages would be used by workers to buy other things in the economy (high velocity). The gold in his vault just sits there (low velocity).

Economic troubles result in low confidence and low velocity of money. Central banks pumping money into the economy somewhat offsets this. As long as the overall velocity of money matches the productive capacity of the economy, there won't be high inflation. One concern of course is that central banks cannot control the velocity of money, so if all this new money gets velocity we could get high inflation that central banks cannot control.

Now think about where you mentioned soaring prices. Many of these are places where rich people can store wealth at low velocity: real estate, fine art, gold, etc. So yes, the effects very much are connected.
