Actually I gave it some thought. PPP makes sense and that what should be used. Let’s take the fictional example of a team of builder building a house. The exact same, basic house. The same team of people, build 3 houses One in the Silicon Valley somewhere full of rich tech folks that they are gonna overcharge. One other in Columbia ( same exact house ) One other in Germany ( Same exact house, built in 2000 man hours all 3 of them ) The productivity of that fictional team of builder is the same. They output one single house in 2000 man hours. But they might sell the house for 10 times more USD in the SV than in Columbia and 5 more than Germany. Skewing the measure of their raw productivity. Hope it makes sense
