Upvoting because, to be honest, the moving electrons/moving dollars analogy works really well for me, and especially I think that's a useful analogy. For a society, in general, dollars sitting idle in a bank account instead of being spent on something constructive or services where someone is getting paid for work or something of utility is being built/created are not, from my perspective, useful to that society. Sure, someone's balance sheet might be achieving larger-and-larger numbers, and that serves their own purposes, but not those of greater society.
