$289,017 a person just doesn't cut it, or even come close to covering the lost income. Let alone cutting the passengers lives short...
So the $289,017 is over by about a factor of 14.
The Lion Air victims were almost entirely Indonesian nationals. Indonesian GDP per capita is $3,800/yr.
I get your point, but I don't see any windfalls here. On the face of it, $100 million seems more at the very low end of what might arguably be considered reasonable compensation. The high GDP nationals from the Ethiopian Airlines crash are likely to take a large chunk of that $100 million. Plus people flying, especially those resident in those areas, likely have above average incomes. Seems like Boeing is low-balling. They basically said as much: "We hope this initial outreach can help bring them comfort."
