$90M goes a lot further in India, though. But yes, you’re still correct that this mission doesn’t prove that private is cheaper. I’m sure that Intuitive Machines took a big loss on this in order to get the deal, and it still cost this much.
Does it? For the person who cleans that restrooms that money goes a lot farther. For the quick boot camp and we will write html it also goes farther. However for the good engineers it doesn't go nearly as far. Great engineers in India are in demand and their prices have gone up to match. I wouldn't attempt a project like this without a lot of great engineers. (Great engineers in India make less than the US equivalent, but the difference is narrowing)
You are correct, the costs of salaries alone should show a significant difference. I wish people would actually have real conversations about what things actually cost per country. It's disingenuous to compare the USA and India without a true cost analysis
