Teachers didn't play back then.

"Hello Mrs. Johnson, I had to beat your son this morning for publicly stating that he didn't want to do his homework. No, no, I already had the switch prepared for him, it didn't take any time away from the class. Oh, and I made sure to give him an extra assignment just in case he was getting bored at home"

That's incredibly reductionist and misleading.

Most people become rich by being good at a job or skill that makes them essential, either easy to be hired or hard to get fired. After that, the majority of people gain weath over time until they erase all non essential debt (house or insurance payments), and then have enough on hand savings in order to diversify their income sources.

In other words, although the majority of stockholders don't actually possess the skills to run a company they have invested in, they didn't just get born with a $1,000,000 in Microsoft. They invested after they became financially self supporting.

A very few (less than 10%) actually have generational wealth. The majority of others (I believe it's around 70-80% though i can't remember the actial number) get rich by working steadily and paying off their debts.

Even in prehistoric times, when all of this domestication was going on, the average spider only ever reached the size of a housecat.

While cats on average reached the size of persons.

I feel like it's more that cats as predators can kill many household pests without a lot of backup and also clean up after themselves, while spiders generally have more specific diets with more specialized hunting methods, and instead of cleaning up after themselves, they leave the crushed and drained bodies of their kills wherever they finish their meals.

Also, prehistoric man probably compared the animals in a face-off and said "if I could have one animal as my friend, I'll take the gigantic furry killing machine that takes care of its young instead of the one that I have to chase out of my shoes every morning"
