In the presentation it talked about college, even a short amount, can give better outcomes.

But the presentation was more of an overview of the issue, and I don't think it's fair to argue that, because it doesn't go deeply into every data point, that it's not valid. It more about bring awareness to the issues, and grounds for further research.

It shows that family/environment influences life outcomes (it should be obvious); it's not conclusive (in establishing causation), it does show a correlation. I really think it's almost obvious this is true, but it's important reinforcing with data nonetheless.

So you can break (or weaken) the cycle if you improve those conditions, and this improvement propagates.

> It shows that family/environment influences life outcomes

Not to nitpick but this statement implies causation (family environment causes life outcome) which you contradict right after.

Sorry to sound obtuse, but, I asked because it may seem obvious to you, but it's not so obvious to me that there will be much improvement. I've seen data that indicates that outcomes are not changed (much) when those early interventions / "investments" are made. There is _an_ improvement, but not to the level people expect. Like a person's height, access to high quality food will only do so much; some people are just going to have short stature however much money you invest into making sure they have access to nutritious meals.
