"that can never be arranged"

"Of course, he's right, your dear old dad:

The world is poor and men are bad.

An earthly paradise might be arranged

If this old world of ours could but be changed

But that can never be arranged.

Your brother might be fond of you

But if the meat supply won't do

He'd cut you down right where you stood.

(We'd all by loyal if we could.)

Your good wife might be fond of you

But if your love for her won't do

She'd cut you down right where you stood.

(We'd all be grateful if we could.)

Your children might be fond of you

But if your pension would not do

They'd cut you down right where you stood.

(We'd all be human if we could.)"

-- Bertold Brecht, The Threepenny Opera
