Nice! I agree with the principle - it works quite well in many areas where these optimum points are nearly static. When they are not - it's a much trickier proposition.
What's a good example of a situation where the optimum points are non-static? High and low tax states? In any case, when trying to solve an optimization problem, static or in flux, it's best to look at the extremes first. Useful way to solve these problems quickly.
That’s one, but in general - anything involving socio-economic factors. Optimal choice of a university, employer, city, even country of residence - all of these can and do change, often quite dramatically. Hong Kong is one such example that is being played out right now.
Obviously agree about looking at extremes first - indeed useful in understanding any phenomenon.
