I have already explained labor shortage. And yes, when you have a growing economy you don't get babysitters: you need kindergartens. Anyone can get a babysitter in India. Almost no one can get one in Japan (where there is labor shortage, no immigrants, and no systematically poor underclass). Babysitters are a thing in either very poor or very unequal country, if anything, a middle class person being able to afford a babysitter is a very, very bad sign for a country. Cost of living means cost of labor (because for anything else productivity is unlimited), expensive place = well-developed, rich place. Energy shortage in a rich country can be solved through renewables and energy efficiency and only country i can think of which is better suited for that than Netherlands, is Denmark (maybe).
