This is very much the case. The standard operating procedure, and overarching strategy of their infiltration and manipulation to subjugate and suppress humanity, is to employ the strategy of divide and conquer. So what you are alluding to is the division stage of that two-part strategy. To weaken, through increasing divisiveness by the parties having a wherewithal, causes them to expend their energies on useless squabbles, conflicts, overcompetitiveness, and even acts of destructiveness that backfire as well, cause legal complications, and reduce overall efficiency, with much wasted effort going into hostile activities that end up backfiring and limiting the support of others. Whereas, if the organizations and companies known for their excellence and productivity kept up that example in an evenhanded way that rewarded all, it would be truly a triumphal example of human ingenuity, initiative, and the ability to make great things happen by being determined and dedicated to a worthy cause. But friction between the labor and management sides of things is like giving a poison pill—things will grind to a halt—it will lead to much ill will and bad blood that can persist for a generation and even beyond, as it gets handed down in the lore about how the powers that be cannot be trusted, the workers are compromised and belittled, and treated like underlings and even slaves, and so on.
The interlopers are quite adept at using politics for manipulation, it is how they run their own worlds. What they do to one another is tragic, it is very much akin to a den of thieves who cannot trust one another and end up following the strongest leader who, inevitably, will be the ruler by being the most brutal and most powerful through ruthlessness and criminal cunning. They apply the same strategies and tactics in manipulating human beings, through mind control, to think like they do, to be petty and mean, and prize being able to get away with things, in believing their cause is just so anything they do is fully justified, so there is no need for misgivings or guilt. This coarsens things and cheapens life. They promote all kinds of ideological campaigns to cause a rift and divide groups to mistrust and dislike one another. On and on it goes, one thing after another becomes a bone of contention, and people are forever struggling to even tolerate existence of one another, let alone doing something in a cooperative fashion that could catapult them forward with progress.
You can see in the current political landscape how destructive it is to have political gridlock generation after generation with the major parties hating one another and unable to compromise and agree on much of anything. That ability to reach common ground is subverted because people's minds are manipulated to disbelieve what they see with their own eyes and hear with their own ears, and have a completely different interpretation of what takes place. So being unable to agree on causes for problems that exist, let alone potential solutions, there can be little forward progress as political leadership keeps changing and is often hampered by the opposition party so they get little done even when technically, they are in power. This is what hit the so-called "Rust Belt" with a vengeance and is an apt description because it was raw vengeance on display to lay waste to that region of America and all in the area and depending on the economy.
