The bourgeoise know very well that resources are finite. That is the reason why the stock market exists, i.e. speculation economy. It allows them to effectively inflate the value of all commodities and extract the surplus value when stock is growing. When the bubble bursts, which they know it will, they still come out on top due to how they have rigged the game. Do not mistake all of them for fools, they have after all the money to buy all the brains they need to understand and make the economy work in their favor.
