Every dollar Wall Street takes from Main Street is spent on getting better at taking dollars from Main Street.

From Wikipedia:

Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns.[2] Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish itself. The term applies to various natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks, and other wildlife.

Wall Street is based on financial speculation & moving digits in databases, Main Street lives with real material constraints like gas prices at the pump & food prices at the grocery store instead of future contracts for oil barrels. Article talks about concentration of wealth in fewer corporations with deep pockets but that's again more moving of digits in databases instead of anything to do with physical constraints like declining EROI of fossil fuel deposits.

The divergence between a "booming Wall Street" and a "stagnating Main Street" is a complex phenomenon driven by structural economic shifts and corporate strategies that favor large, established corporations and financial markets over small businesses and average wage earners.
