A lot of the current education system aims to give children skills that they can apply to the job market as it existed 20 years ago or so. I think children would be better-advised to master more general skills that could be applied to a range of possible rapidly changing worlds: character skills like resilience, flexibility, industriousness, rationality, social responsibility, attention, caution, etc.
Come to think of it, such skills probably represent more reliable “investments” for us grown-ups too.
An influential ethical philosopher is on his way to address a conference of wealthy donors about effective altruism. His rhetorical power and keen arguments are such that he can expect these donors to reach deep and double their donations to yet worthier causes after his talk. On his way to the conference, however, he comes across a child drowning in a pond. He is the only one around who can save this child, but to do so, he would have to jump in the pond, ruin his humble but respectable second-hand suit, and miss the train to the conference. While he would certainly have a good excuse to give to the donors, before he would have the opportunity to do so they would probably leave the conference feeling resentful at the waste of their valuable time, rather than generous and inspired. He figures he can save more lives by letting the child drown and instead catching his train to the conference, so he turns his back on the pond.
