More On Marx's Criticism of Capitalism

Umair Haque takes up the argument made by George Magnus (via Mark Thoma):

Let's take Marx's big critiques of industrial age capitalism, one by one (and with a grain of salt: since I'm far from a Marxist economist, it's entirely possible my quick, partial descriptions leave much to be desired).

Immiseration. Marx claimed that capitalism would immiserate workers: he meant that labor would be "exploited" — not just in a purely ethical sense, but in a narrower economic one: that real wages would fall, and working conditions would deteriorate. How was Marx doing on this score? I'd say middlingly: wages in many advanced economies — notably, the most purely capitalist in a financialized sense — have failed to keep pace with productivity; not for years, but for decades. (America's median wage has been stagnant for roughly 40 years.) In macro terms, labor's share of income has plummeted, while the lion's share of growth has accrued to those at the very top.
Crisis. As workers were paid less and less, capitalism would be prone to chronic, perpetual crises of overproduction — for they wouldn't have the means to purchase or invest in enough goods to keep the economy humming. As Marx put it, there was likely to be "poverty in the midst of plenty." How's Marx doing on this score? Not bad, I'd say: the last three decades have in fact been characterized by global crises of what you might crudely call overproduction (think: too little demand chasing too many disposable widgets, resulting in a massive global debt crisis, as vanishing middle classes took on more and more debt to compensate for stagnant real wages).
Stagnation. Here's Marx's most controversial — and most curious — prediction. That as economies stagnated, real rates of profit would fall. How does this one hold up? On first glance, it seems to have been totally discredited: corporate profits have broken through the roof and into the stratosphere. But think about it again, in economic terms: Marx's prediction concerned "real profit," not just the mystery-meat numbers served up by beancounters, and chewed over with gusto by "analysts." When seen in those terms, Marx might be said to have been onto something: though corporations book nominal profits, I'd suggest a significant component of that "profit" is artificial, earned by transferring value, rather than creating it (just ask mega-banks, Big Energy, or Big Food). I've termed this "thin value" and Michael Porter has described it as a failure to create "shared value." Replace "declining real profit" with "shrinking real value" and it's analogous to what Tyler Cowen and I have called a Great Stagnation (though our casus belli for it differs significantly from Marx's).

He has a couple more points.  The question is, if Marx didn't have the right solution to the problems, what is the right solution?  I don't think I have too many ideas on that score.  Several things figure into the problems, globalization, income inequality, insufficient return to labor, resource limitations, complex societies, rent-seeking, etc.  The long-range world view is pretty complex, and in my opinion, doesn't look good for the Western middle class.  Hopefully, some folks smarter than I can come up with some solutions.
