Analysis of Twin idols

There are two phrases, you must know,
 So potent (yet so small)
That wheresoe'er a man may go
 He needs none else at all;
No servile guide to lead the way
 Nor lackey at his heel,
If he be learned enough to say
 "Comme bien" and "Wie viel."

The sleek, pomaded Parleyvoo
 Will air his sweetest airs
And quote the highest rates when you
 "Comme bien" for his wares;
And, though the German stolid be,
 His so-called heart of steel
Becomes as soft as wax when he
 Detects the words "Wie viel."

Go, search the boulevards and rues
 From Havre to Marseilles--
You'll find all eloquence you use
 Except "Comme bien" fails;
Or in the country auf der Rhine
 Essay a business deal
And all your art is good fuhr nein
 Beyond the point--"Wie viel."

It matters not what game or prey
 Attracts your greedy eyes--
You must pursue the good old way
 If you would win the prize;
It is to get a titled mate
 All run down at the heel,
If you inquire of stock effete,
 "Comme bien" or "Wie viel."

So he is wise who envieth not
 A wealth of foreign speech,
Since with two phrases may be got
 Whatever's in his reach;
For Europe is a soulless shrine
 In which all classes kneel
Before twin idols, deemed divine--
 "Comme bien" and "Wie viel."
