Do you think the decline of Britain started in the 1960s with degenerate music from the Rolling Stones, Beatles and the hippy culture?

The 1960s certainly I troduced  drugs into the middle class. I remember in the 1950s middle class white kids, never heard of marihuana. Heroin was something "the colored people did, in Harlem".

It started after WW2 not in the 1960s.

No.   And none of that was important.  The rot set in with the post war generation and the music and floppy trousers were nothing to do with it.

Britain declined after WW2 when they let the Caribbean's, Indians, Pakis, Bangladeshis, Africans, Roma, Gypsies, Arabs, Turks in. Bad mistake! Britain should have followed the Australian example of Whites Only immigration policy. 

Mass vagrant immigration 

Explain what you mean by decline. 

There has always been an underclass, they are like the upper class but with no money.What you call debauchery has always gone on, I suggest you read some history.You could start with easy history in the form of historical biographies.Try one about the Curzon sisters, all of whom, along with their stepmother, committed “debauchery” with the leader of the British Fascist Party, Oswald Mosley.Ignorance must be such bliss for those who espouse it. It’s just tedious for the rest of us,

no.  poor kids tried to get out of a bad situation with music.  it is better than what folks do in the usa, stealing tv's

Nope.  That was just a change in music. A liberation of what could be said.

well before that , they imported blacks to do the menial jobs as conductors on the buses in the 50's , and india kick them out in 1947 ..

1950 was about conformity - dressing like oldies before your time!

Hypocrisy!

"What will the neighbors say" mindset!

Bowing and scraping! Knowing your place in society! To suck up to those higher classes!

Who didn't necessarily have any more intelligence, manners, merely the recipient of  an  accident of birth!

No different from king Louis or Czar Nicholas being ordained by God!

As if!
