Correct. They are merely groups of people who are in charge of substantially powerful entities and corporation who collectively control mostly everything.
Their power stems from the ability to fund candidates and control most of the mainstream media.
Donald J. Trump doesn't require their imprimatur, hence remains a threat to them. They aren't all powerful. Yet powerful enough to enlist/bribe/order DAs and committees so as to maintain a steady persecution of the man in perpetuity.
Yes there are a lot of private groups with influence.
AFL-CIO
NEA
AARP
NRA
Catholic Church
AMA
Free Masons
And its no “conspiracy” for these groups to use their influence.
