It's strange how we take interest on cash as a law of nature, when the original intention might have been nothing more than compensation for the risk the lender was taking on.
Now the risk (on bank deposits, govt bonds etc at least) has effectively been removed so the interest rate is the baseline expectation.
So compound interest is underpinning the infinite growth forever delusion...
This is also why the market tolerates destructive private equity firms: their sole purpose is to create growth in the second derivate; that they 'pull up the ladder behind them', so to speak, by killing the business and terminating investment gains for investors in the first-derivative tier (market stockholders) and zeroth-derivative tier (capital investors), and that they kill great products in a market so that buyers are forced to buy shitty products, are recursively beneficial to more efficient cycles of vampirism.
