EMJ on Wagner and Tolkien

From Chapter 78, pg 1061, of EMJ's "Barren Metal":

The ring has given Alberich terrible power over his fellow dwarves:
Nibelungs all,
bow down to Alberich!
Everywhere now he lies in wait
in order to keep you under guard;
rest and repose
have melted away;

That power is that much more terrible because it is invisible; something Wagner symbolizes by the Tarnhelm, which Alberich put on before he delivered his speech. The fundamental meaning of the Tarnhelm, the helmet which renders its wearer invisible, is taht the Capitalism as it is actually practised is invisible to those who suffer from its effects. "No one sees me," says Alberich:

No one sees me,
though he may seek me;
yet I am everywhere,
hidden from sight.
for him you must toil
where you cannot see him; where you don't expect him
there you shall find him:
you're subject to him for ever!

G.B. Shaw claims that the Tarnhelm, the helmet which renders its wearer invisible, is quite common in capitalist centers like London:
"which generally takes the form of a tall hat. It makes a man invisible as a shareholder and changes hi into various shapes, such as a pious Christian, a subscriber to hospitals, a benefactor to the poor, a model husband, and father, a shrewd, practical independent Englishman, and what not."
