1) The Fed β This is the "push" or force that starts everything. The Fed runs U.S. money rules, like deciding interest rates or adding more money to the system
2) Lever: Inflation β This is the tool that makes the push stronger. When the Fed adds more money, it usually causes inflation. That means money loses value over time (debasement), and prices for goods and services increase. I found a non-USA Example here :D

3) Fulcrum: The Middle Class β This is the support point that takes all the weight ie the hit! In a real lever, the fulcrum handles the main pressure to lift something. Put another way the working people (the middle class) get hurt or squeezed by the bad sides of these money rules. They can escape if they own hard assets.
4) Load: Asset Prices β This is the heavy thing being lifted up. Things like stocks, houses, and other investments become more valuable due to the increased money in the economy. Those that own the rock as in this image do well.... those that do not - suffer.
