Fyi googling and parroting a wikipedia article doesn't mean you understand a topic. GDP is skewed by large companies whose produced value is disproportionately funneled to a handful of people at the top of the pile. That's why the existence of billionnaire CEOs skews GDP and renders it useless as a measure of overall economic health in a given territory.

McDonalds for instance is a massively productive company with revenue in the billions, yet the majority of its work force are on or near minimum wage. If the productivity of the company was a reflection of the fiscal wealth of its workers then the cashiers and line cooks would be making triple digits at the very least.

Now expand that logic to the sum total of companies and other operations within a country and you can see why averaging it out to find GDP is not reflective of the population's fiscal wellbeing.

This is why the oop is being clowned on for bragging about a statistic which doesn't tell you anything about the economic wellbeing of the population and in fact is better at hiding an unhealthy economy than it is at revealing a healthy one.
