The game developer Pirate Software had a video on this. He mentioned that the demo for his game, Heartbound, was really popular in Brazil, but due to Brazilians not having high purchasing power, the final version was too expensive for Brazilians to buy. So he lowered the price of the game in Brazil and added Portuguese translations to the game, and the game now makes 25% of revenue from Brazilian players (also it increased the total amount of revenue and reduced piracy, I think)

The general idea is based on charging people based on how much they can pay. There are reasonable ways to execute this (I’d argue localized pricing is among them, along with things like open source software and donations, and financial aid at colleges) and unreasonable ways (like Kroger’s bid to use facial recognition to do it in their stores)

Price discrimination is a subject covered in introductory level microeconomics courses:

Bottom line is collect more money from those able and willing to pay you more, and collect less from those less able and willing to pay you, as long as it is above the cost of goods sold.

At some national parks or attractions in poorer countries, they will ask to see your passport and collect more money if you are from a richer country.

I haven’t read the piece, but if someone makes a well-reasoned argument, it doesn’t matter who they are or what credentials they hold.

It’s equally as meek a counter-argument as, “trust me because I hold degrees in this topic.” Good. Then it should be easy for you to make a well-reasoned argument.
