on economic issues, tax policy, and foreign policy, we've been moving steadily to the right, sometimes by leaps and bounds, since the 80's.
you can see this not only by looking at the control and makeup of federal offices, but governorships and state legislatures as well.
to the extent anyone wants to complain about the situation they find themselves in, it's clear the sort of policies that are behind it.
Tax policy, the top marginal tax rate before the 80s was about 70%, and since then it's been about half that, so if this represents a move to the right, I agree.
There is a really good and important movie that came out this year,
The Post, about how Daniel Ellsburg stole the Pentagon Papers from the Rand Institute, and turned them over to the media for publication (spoiler alert).
Basically, the Pentagon Papers were compiled by Secretary of State Robert McNamara, and they chronicled what a clusterfuck the Korean and Viet Nam conflicts were, under the direction of five different presidents of both parties, and their administrations - and everybody on the "inside" knew what a worthless clusterfuck was being perpetuated, and nobody wanted to "fess up" to it on their watch.
McNamara had been chronicling these for perpetuity, in the hopes that academics in the future would have access to this information.
Anyway, Viet Nam ended right around 1974...and there were no more clusterfuck wars until around 2000, and now it's 2018 and we're still kind of cluster fucking around.
So anyway, as far as foreign policy...I would say it really hasn't gone right or left.
I don't know what you mean by economic policy moving to the right.
As far as Federal Offices...if by that you mean the Congress...also governorships and state legislatures...the most prominent feature that applies to all of them is...they're all elected by voters.
So if you think the country has been moving to the right since the 80s...according to your final statement in the post I quoted here...it's the voters in our Democratic Republic that are moving it that way.
