The rich have always had disproportionate power, but historically there was a lot more top-down violence. When the US started out, it was generally only land-owning white men who could vote, a pretty small proportion of "the people". It took decades past your "200 years ago" to get a vote just for the minority of people who were white men, and it was a very bumpy process. E.g.: https://en.wikipedia.org/wiki/Dorr_Rebellion
It wasn't until about 100 years ago that a majority of "the people" could even vote, and it was only 50 years ago that saw voting and economic rights applied reasonably equally to a majority of "the people".
Or we could look at actual attempts at "the people" having a modicum of power: labor organizing. The US has a rich history of anti-labor violence: https://en.wikipedia.org/wiki/Anti-union_violence_in_the_Uni...
I am happy to complain about what's going on today. But as bad as, say, Amazon is about union organizing, we shouldn't pretend that it's (yet) as bad as it was for most of America's history. And part of what makes today better is a strong-enough set of governments to push back against corporate malfeasance. As the police in this story clearly did.
Until very recently, the idea that those with power could not use that power to extract whatever they could from those without power was laughable. And the shit that the common folks had to deal with hundreds of years ago makes the worse harassment of today seem completely benign. Hell, mass murder to make a few bits of extra gold was common. And no one really batted an eye. Sometimes society not only condoned it but celebrated it.
Not to say that harassment today should be ignored. But harkening back to the good old days that never were is not, IMO, the way forward.
Short story is that this was a private agency that openly offered services like the ones performed by the Ebay contractors, all the way to the point of directed murder, and did across decades, within living memory.
Nowadays, such services are offered mainly in war zones, by companies like what used to be called Blackwater, later Xi, run by Erik Prince, brother of Betsy de Vos. So there is still a market served, just a bit more circumspectly. But nobody who hires them goes to jail, and they don't either.
200 years ago, if the people in power were acting up, the people had the capacity to act...and they did. Heads fucking rolled. And not just some heads, but a lot of heads. Present day, the state is more powerful than people 200 years ago could even begin to conceive of. We have trillion dollar companies that literally do whatever they want. The people have little recourse to do anything anymore (there's a panoply of reasons as to why that's the case, but that's besides the point). We inherently know violent resolution is not the way to go...but let's be honest: nonviolent resolutions aren't working anymore.
