Yes, the labels 'right' and 'left' are not satisfactory really. Very broadly (and not including the extremes of either), 'right' could be said to mean those in favour of not changing things too radically, and of letting people live with minimal interference from the state, while 'left' might mean those in favour of changing things in order to achieve a more equal society (eg through the redistribution of wealth).
The problem is that corporations have now have such a grip that whichever candidate ('left' or 'right') gets in, THEY remain in control.
For example, Tony Blair was supposedly on the 'left' but look at his record - hugely wasteful PFI schemes, pointless wars, privitisations - all put public money into the pockets of corporations and arms manufacturers. Then again, the privately-educated (psychopath?) Blair had no left-wing leanings whatsoever.
Margaret Thatcher did much the same and worse, but made no attempt to appeal to the 'left' or 'centre'.
In the US, the media is even worse than it is here, to such an extent that the word 'socialist' is only ever used perjoratively.
Many in the UK pinned their hopes on John Smith, a true 'lefty', who died before he could be elected. He would have probably won, such was the dissatisfaction with the Conservative government at the time.
For a clearer picture, I recommend John Carpenter's film, 'They Live'. Also the Adam Curtis film 'The Trap'.
I don't know, the rot may even have started with Edward Bernays...
