it looks like getting divorced, or one couple quitting job before kids are going to apply for college, or having unlimited kids, are the right strategies for the best colleges application than otherwise. I actually know one family did just that, the college-educated mid-age mom quit her job so her daughter got all the financial support from Harvard, and she is walking her dog on the community daily to stay fit now(instead of working). I am not sure if she will be back to work after 4 years when her kid graduates.
Basically, the more screwed your (family) situation is, the more helps are there for you for free, even for the most prestigious universities admission! only the sky is the limit.
