You want to try again? The facts haven't changed since last time.
Never claimed that they have.
Regardless of the time this "really" started, the adoption of right wing economic ideology has fueled it in no small way. Holding to that ideology won't make it better. It just makes it worse.
You can go on about Dems, Clinton & Obama all you want. In the sense that their economic policy is flawed it's because they accept too much of it themselves.
It's still right wing economic ideology to some degree or another. It still leaves median families with a 40% smaller share of national income than they enjoyed in 1978 and the top .1% & .01% with massive multiplication of their share.
If the rewards of the system were equitable back then, what justifies them being different today? Why should they be?
If American workers have to settle for less, why should the people at the top be allowed even more?
