It'll enforce schema and destructure the nested dict/list that results from JSON decoding.
The trouble with linear methods is that they often fit to the bulk of the population and have poor fit at the extremes.
If smart students choose selective schools and smartness is associated with ROI, we would expect to see a correlation between ROI and school selectivity. That we don't is interesting.
If merit is highly correlated with school selectivity, then selectivity can be considered a proxy for smartness/determination/etc. If that's the case, education ROI appears to be not strongly correlated with merit (via the selectivity proxy). That is very interesting.
The author was addressing the opposite situation -- people using more than what they pay for.
> It would be just as ridiculous to write an article about how "people with children in schools aren't paying the cost of the school"
A more similar analogy to what the author was pointing out would be that current taxpayers will receive more Social Security benefit over their lifetimes than the future value of their lifetime payments, meaning that the system is only financially sound if we assume the working population will grow at an appropriate rate such that we'll always have enough workers to pay for retirees.
Or, adjusting the analogies you provided: we are borrowing from other countries to pay for our schools and fire departments. This happens to be true. Is it bad? Unknown.
