Do you have another study?
Either way, it's a fact that parental income is the best predictor of future income. Not educational attainment.
But why? What are the CAUSAL relationships between parental earnings, educational attainment, and child earnings? The children of doctors are more likely to become doctors, but saying that educational attainment is therefore less related to doctoring than parental occupation is obviously a bit absurd. Just because a parent paves the path doesn't mean that educational attainment is irrelevant to walking that path. And anyone who makes it through med school and residency has the option to enjoy high earnings, regardless of parental income.
The MD example, for the curious and humble reader interested in Truth rather than Winning, makes it abundantly clear why section 3.6 of the linked paper asks a question that's directly relevant to untangling these causal links.

There's an entire literature base on exactly this question. "lifetime earnings parental earnings education" returns 130K results on Google Scholar. But, to be blunt, I don't think you're interested in learning anything. I think you're interested in Winning the thread. So I'm not posting for your benefit; that would be futile. I'm posting for the benefit of intellectually curious readers.
What you want is a study that shows that people from lower income quintiles that go to college have a higher lifetime earning than people from the same quintile that didn't go to college. Maybe that exists? if it did, I'd imagine the pro college people would be waving it around everywhere.
Using Google Scholar to find relevant research is a great habit. but you really have to read it to make sure it says what you think it says
Yes, there is a large college wage premium for students in lower income quintiles. The most that can be said is that it's smaller, but still quite large.
I assumed the point of contention was a more nuanced question about causation, since the above is just a simple factual question that can be checked without any sort of analysis.
Social network, safety net, family experience with college, etc.... There are plenty of reasons why class mobility is imperfect. [Edit: I, for example, had access to summer jobs in highschool through my parents' professional network that were not as easily available to other people.]

Yes, but you chose a specific article to post to refute a specific claim. The article doesn't address that claim, so it is entirely reasonable to ask for a citation that does actually back up your argument. Your response here amounts to: "just go read the all the literature until you see I'm right" and is not constructive, even without the name calling.
Edit: You seem to have substantially edited your comment. Thanks for removing the name calling but generally ghost edits like this are frowned upon here.
Yes it does! I think you're misreading OP's post.
What was OP's claim?
>> The most accurate predictor of a person's lifetime income is the income of their parents. Children of wealthy parents are more likely to go to college. It's like saying "People who drive expensive cars in high school make more money over their lifetime, period".
OP's assertion about "best predictor" is true but irrelevant. The interesting question is why?
OP asserts that the answer to that question is literally "for the same reason that rich kids drive BMWs".
OP is asserting that college has the same causal effect as a parent purchasing a BMW for a child. I.e., none at all, it's just a proxy for parental wealth.
That strikes me as an unlikely causal hypothesis.
Could there perhaps be a reason other than parent income that the child of an MD drives a BMW to school? Probably not.
But could there perhaps be a reason other than parent income that the child of an MD does well in their premed program? Seems likely.
And indeed, the above article establishes a causal link that's directly relevant to falsifying that assertion, that college == bmw in terms of causal effect.
Elsewhere, OP asks if the college wage premium persists across family backgrounds. I think perhaps something related to that question is what you perhaps read into their post. But that's not actually the claim they are actually making in that post.
(BTW: CWP and PEP are positive for students from low income backgrounds... these are just numbers you can look up... why am I the thread secretary for basic statistics?)
Sure, but they are interrelated factors and they way they effect the distribution is complicated. This study was linked elsewhere and does control for parent's income: (I didn't vet the methodology or data, just looking at what their reported results say.)

One of the reasons that parental income is such a strong predictor of child income is because parental income has a strong effect on how much college will increase your income.
Interestingly enough, that effect is quite disparate based on more than just parental income.
The study says that low income whites see only a 12% boost to income from college while high income whites see a 131% boost to income from college. Interestingly, blacks show an even higher boost to income from college, 175%, and parental income had no statistically significant effect on this boost.
Also interesting is how those effects play out when you look at different parts of the income distribution. Parental income increases the average effect of college, but doesn't significantly affect the median effect. Thus a lot of the increase to the effect of college on average incomes [edit: for children of higher income parents] is from gaining access to the long tail of very high income outcomes.
So the answer is if you are a poor white male, college is far less valuable than if you are female, rich or black (in increasing order of college effect size.)
