The thing about the "money" argument is that one could just as strongly claim that you went to 1st grade "for money".

except that there is a certain lack of autonomy both legally, mentally, and physically that prevents first grade aged children from refusing to go to school in many nations.

In other words : you can't derive a motivation from an action an individual does if it's something that they're forced to do so socially or legally.

And at the end, we end up with the capitalists dream: "I was born... for money"

I was born into debt. Then, I was forced to go to schools that taught obedience to authority, getting a job, and paying taxes. Then, I saw ads that told me I needed to buy products and run up debt. Then, I eventually didn't care about money except where absolutely necessary.

Everything in between made it seem like making money my No. 1 focus was necessary, though. A lifetime of being manipulated and pressured. It all gets better when you can finally pull back the curtain seeing what's really there. :)
