So the formula is to make everything equal, at all times.
Simple Mathematica function that ignores all other factors.
So an example would be a three generational family.
Grandma and Grandpa are retired with paid off mortgage.
Their only son had three kids, one married and out of the house, two other late teen kids at home.
Married kid has spouse and baby.
So obviously all have different income levels, different needs, different amount of debt.
The formula just assumes all three households spend/consume at same level.
So the grandparents utility usage should be the same as the others, regardless of house size, etc.
The US is 4 percent of population, consume 25% of the goods. How the hell can Canada with less population ever consume at our level. Even if they increased consumption to our per capita levels they still couldnt match our levels.
Australia is even more glaring example. A population about equal to Southern California, we have a trade surplus with them, but trump still slapped the minimum 10 percent tariff on them.
So in the family example, that third generation family, if diapers and formula are imported, they would pay a 10% tariff.
No logic to the formula to consider population, wealth, etc.
