The US is massive and each state and city can have wildly varying costs of living and pay.

So it’s a bit hard to compare someone from NYC to someone who lives in Austin Texas.

Generally on the north east coast the cost of living is high due to density and so wages/salaries tend to be higher than somewhere with a lower cost of living. As you move into the mid west and central US things tend to come back down before going up again on the west coast.
