1) It's a visible hand now. Adam Smith was a while ago and much has changed across economics. Enough that what you'd think are timeless truths have also become false.

2) We have a name for this hand - the federal reserve of the united states of america. If you saw the last Mr. Robot season, there's an episode where Mr. Robot says "behind every great fortune lies a great crime, this is the corporate motto of these United States". He was only slightly wrong. Behind all great fortunes since the advent of central banking lies the hand of the federal reserve.

Or 4, with capital deepening and lowering long term GDP growth (and the impact on interest rates that has), asset values trend upwards ever so slightly over time. And of course you have bubbles of valuation.
