Poor kids who do things right don't do better than rich kids who do things wrong

    "It's an educational arms race that's leaving many kids 
    far, far behind."

This isn't a bad thing. It's an educational arms race that is moving the human race forward faster. Communities that have placed emphasis on education early on have not only typically outperformed their peers, but also add a lot to human knowledge.

    Nobel Prizes have been awarded to over 870 individuals, of 
    whom 185 - over 21.264% - were Jewish or people of Jewish 
    descent, although Jews and people of Jewish descent 
    comprise less than 0.2% of the world's population (or 1 in 
    every 500 people).

Furthermore, I don't understand the criticism regarding "opportunity hoarding". I don't have children yet, but I hope to have children in a few years once I've built the amount of wealth I would like to have before embarking on that adventure. I don't yet feel like I've built the amount of wealth necessary to provide my children with enough of a competitive advantage to succeed in the 21st century. If I've worked hard to create opportunities for my children, why should I give them away to someone who is not my child?

It's not "rigging the game". Saying that it is rigging the game is a misunderstanding of the game. The game spans multiple generations. The game isn't reset every generation. That's not a game I want to play. My parents were my teammates and my children will also be my teammates.

The criticism of pitfalls out there (e.g. degree mills, payday loans) that entrap and deprive people of opportunities is totally fair, but criticizing the decision to spend the wealth one has earned to their progeny seems like wanting to change the rules of the game.

Wealth inequality itself isn't the problem. Not having access to basic necessities (health, education, sustenance, shelter and the Internet) upon which an individual can start building their wealth is. I think it's reasonable to pay a certain amount to level the playing field at the bottom so those that are determined and principled can reasonably begin creating wealth, but that's a totally different goal compared to reducing wealth inequality. Basic income for example would be a great way to begin meeting needs so individuals can start building wealth.

If wealth inequality were the problem, the 10% should complain about the 1% and the 1% should complain about the 0.1% and the 0.1% should complain about the 0.01%, so on and so forth.

I was just getting ready to make a reply along the lines of who cares what outcomes for rich kids are as long as there is opportunity for non rich kids. That is to say, who cares if little Richie Ritch will succeed 100% of the time because of his wealth, as long as your average poor can succeed provided they put in the work (i.e., isn't denied opportunity).

Your comment took a way different direction than I was expecting and genuinely made me reflect.

You see, I grew up extremely poor (yes, those "hoods" you hear about), and figure it's possible to make it out. But, I do do what you mentioned above A LOT. To the point that some times I feel guilty expensing my cell phone even though it's a perk.

This is a much better analysis on social mobility:

This really hits home for me.

I once had a conversation with a very, very experienced developer who ran a local meetup and was discussing salary options at a new job. He balked when I told them what I asked for, and replied:

"Just because you grew up as poor as me doesn't mean you should fear wealth. If it makes you feel that guilty take the shit and donate it to charity."

And its really true.

My first engineering job I made almost 3x what my mother ever made in a year over her entire life's highest salary.

I was a college dropout that was enthusiastic and knew enough to be functional.

It really is a strange, new thing to come from nothing and all of a sudden be able to go out to eat at an Applebee's without worrying about your finances for a month.

Edit: The first thing I did after collecting my first 'engineering paycheck' was go out to Applebees and get an appetizer, a drink, AND an entree, and then proceed to not worry about it.

Behavioural Genetics isn't a social science and there's nothing in what the poster above you said that wouldn't be in an undergraduate textbook.
