GDP per capita has three flaws:
First, it doesn't count unpaid work.
That includes critical components like in-home child or elder care, volunteer activities, and housework. Many activities that are included in GDP couldn't occur if there weren't these support activities.
Second, it doesn't measure pollution, safety, and health. The government may encourage an industry that spews chemicals as part of its manufacturing process. The elected officials only see the jobs created. The cost may not come to roost until decades later.
Third, the GDP per capita measurement assumes that production, and its rewards, are divided equally among everyone. It ignores income inequality. It can report a high standard of living for a country where only a few enjoy it.
