Is Boston cheaper than New York?

I'm curious, could you elaborate on why you believe Boston may be cheaper than New York? Is it due to the cost of housing, dining out, or perhaps transportation? Have you compared the average salary in both cities to get a sense of the purchasing power residents may have? I'm genuinely interested in understanding the basis for your comparison, as both cities are known for their high costs of living, but may have nuances that make one more affordable than the other.
