Fun fact...if your GDP growth is less than your rate of inflation (currently 3.8%), then your economy is shrinking and you are getting poorer. This also means your standard of living is decreasing.
That would hold up comparing nominal GDPs of subsequent years. GDP growth rates are adjusted for inflation.
Goodhart's law suggests that's not entirely true. GDP is an imperfect measure, and doesn't capture how anxious people are, how happy and content they are. It doesn't measure how much hope they have for the future. It doesn't say how much more or less you make than your brother-in-law.
