GDP per capita vs. the federal poverty rate over the years (observation and discussion)

Fair warning, I'm a dummy trying to talk about stuff I don't fully understand, but I wanted to see others' thoughts on this.

In the 1960s, America's GDP (per capita) was $3,000.
Also, in 1960, the federal poverty limit was $3,000 for a family of four.

In 2023, the GDP (per capita) was $82,034.
The federal poverty limit for a family of four in 2023 was $30,000.

This can't be good for the American people. Unless I'm drawing comparisons between two completely unrelated things?

People who are barely in poverty today would have to earn ~2.7x the amount they earn to stay consistent with those who were barely in poverty in the 1960s if GDP and FPL were still equal to each other. So what about the families caught in the middle? Too high earnings to get help and too low to thrive? They just suffer, I guess.

Out of curiosity, I calculated what the thresholds would be if the percentages of GDP to FPL were swapped between 2023 and 1960.

1960s numbers adjusted if FPL matched 2023's percentage:
GDP=$3,000
FPL=$1,111

1960s numbers adjusted if GDP matched the percentage comparison of 2023:
GDP=$8,100
FPL=$3,000

Please let me know if it actually matters that the GDP per capita is 2.7x the federal poverty limit for a family of four. Also, let me know your thoughts.
