As the HVAC system releases its “wealth” of cool fresh air through the supply vents, it trickles down to people at the lower elevations for them to enjoy
Proponents of supply-side economics, also known as “trickle-down” economics, point to its inherent logic. If the rich become richer, they will either increase their investments or they will spend more. Both investment and spending will increase tax revenues to keep the various levels of government happy. Investments, in theory, will lead to better and higher-paying jobs while the added spending spurs the “multiplier effect”. This is where those who sell things to the rich will enrich themselves and thus increase their spending. This only works if the rich are willing to invest their wealth domestically instead of in an attractive investment option in a foreign country. A Mexican based CNC operator earns about 25% of what an American worker with the same skill set earns. This makes for a difficult choice for owners of manufacturers with employees who have families to feed. One place where the trickle-down theory works like a charm is a house with a central HVAC system with properly placed supply and return vents. As the HVAC system releases its “wealth” of cool fresh air through the supply vents, it trickles down to people at the lower elevations for them to enjoy. The return vents take the warmer air and feed it back into the HVAC unit where the “investment” is again made to cool it once again. The best part is that your HVAC works for much less than minimum wage and can even reverse the process in cold weather where the value of the air is in its warmth and not its coolness. So, if your employer relocates to Mexico or any other country with cheap labor, you can spend your unemployment sitting in the richness of your HVAC controlled climate.
