I agree with you, and I believe in the same. People that help cheaters don't realize that these people put up a sweet face and good behavior just so they can stab you in the back and take all that they can because they view you as a sucker. Helping them doesn't benefit anyone.
Heck, I'd even go as far as to say that large corporations that generate a lot of money depend on just a few individuals of extraordinary merit who are (by naivete or (social) design) incentivized to spread the attribution of work done. This sort of distribution is never equal by design; if the genius (proper definition https://geniusfamine.blogspot.com/) is a 100x-er then there'll be a thousand leeches vying for bragging rights to the work that they aren't responsible for. This is often called "prestige", and is something the west inherited from the third world, where people routinely make shit up and even though everyone knows in their bones that it's made up, they play along. In time, people get too stupid to even know that. If you can induce "prestige" in random people, that's brand loyalty. Someone that can do all of this, capture a bright sucker and put a thousand leeches on him is called a really great ""innovator"", like Steve Jobs and Bill Gates, and who knows how many more. These guys never did much, were handed things on a silver platter and managed to be the luckiest (not in the ironic / "hardwork" manner) guys. Modern large-scale society rewards these people handily because all the extortion and gaslighting of the competent is abstracted away into the "public good" and "shareholder and company value". I don't believe everyone gets a leech or two, because not everyone is able to contribute. Most people can't read above a fifth grade level. Heck, most of finance is based around the upper management servicing their friends at the expense of everyone else. Everything is downstream of that, and most white-collar work is now a scramble just to determine where the most competent people work, and exploiting them (this is done not just the people at the top, but also by their "fellow colleagues"!).
Family is supposed to be exempt from these things. Societies that consider this a given often flourish into first world economies, and remain so as long as they keep the real leeches at bay. Societies that don't never rise from the muck.
It's in the leech's interest to help out others like him.
This also explains the absolute seethe that libertarian viewpoints generate. Reading someone like Ayn Rand actually scares these people because she advocates for people to stop being taken advantage of when there's nothing in it for them. Same for a lot of authors like Rothbard and Mises, they're all "overturned" on their idealism but all the critique of the daylight robbery is quietly squashed (aka never addressed) by the opposition.
Imagine being called a "sucker" by the leeches. Gaslighting at its finest.
