For what it's worth, here's a rough translation of Victor Jara's version. See my previous comment for the bit about polystyrene. The general referred to was René Schneider.

PRETTY HOUSES

The pretty houses of the rich suburb
Pretty gardens behind their gates
A lovely carport at the side
Just waiting for a Peugeot.

Pretty pink ones, pretty green ones,
Pretty white ones, pretty blue ones
The pretty houses of the rich suburb
All made of polystyrene!

And the people from the houses
They smile as they pay visits
Off they go to the supermarket!
Everyone has a TV.

Some are dentists, some are landlords,
Some are traders in import/export,
Some are lawyers, some are landowners,
And they all wear nylon suits.

The play bridge, they drink martinis
And their kids have little pink faces
And with other little pink kids
Off they go to high school

A little later, Daddy's little boy
He goes to the university
To begin his serious studies
Of the complexities of society.

He smokes cigarettes in his Austin,
He plays with bombs and with politics,
And assassinates generals
He's a gangster of subversion.

And the people from the houses
They smile as they pay visits
Off they go to the supermarket!
Everyone has a TV.

Pretty pink ones, pretty green ones,
Pretty white ones, pretty blue ones
The pretty houses of the rich suburb
All made of polystyrene!
