The Proverbial "They"

Life is so care-free, happy as can be...
No decisions to make
There's nothing left to fate
'they' tell you how to look
'they' tell you what to say
'they' tell you what to love and tell you what to hate...
(and still you do what 'they' say)
Life is worry-free, no identity
'they' tell you who you are and who you're going to be
(and still you do what 'they' say)
You do what 'they' say
You do what 'they' say
You do what 'they' say...
(over and over again)
You do what 'they' say
You do what 'they' say
You do what 'they' say...
(but who the fuck is 'they'?)
