You need to account for inflation. Dollar value in 2001 and 2022 is not the same. CPI today is ~295 vs ~175 in 2001, so while nominally today's monthly payment is higher, it is not higher in terms of its purchasing power.
$1,996 / month in 2001 vs $2,972 / month in 2022
That's in today's dollars, accounting for inflation. Almost 50% more. Feel free to point out an error in my math.
