They certainly do. The democrats of today despise the lower income classes and hold them in contempt.Hmmm...I'd take it a bit further...to the Worker's rights struggles early in the last century.
While the two parties now correspond to left and right, this is a relatively new thing. For most of our history, the extremes of both parties were on the outside looking in.
They were wooed for votes and then discarded.
The tea party was the first RW action I took note of.
Now that the Progressive wing of the Dems have control..and the Trump faction rules the Republicans, I'd say the parties, to our sorrow, do indeed represent Left and Right.
Those protests in the 60's were NOT endorsed by the mainstream Dems. Nor was the race issue...until they found they could win with it.
Thr Republicans were the party of the moneyed classes...hillbillies and rednecks need not apply.
Time they do change eh?
