Except you’re a wage slave and your American Nightmare comes with a mortgage, your sizable interest payments are likely funding the retirement income of a boomer too (along with bankers too, they always get a cut)
90K is still 50% above the median income, not to mention the fact that you have twice as much as time available and using just a small amount of that can be used to cut costs significantly in other areas. It is more effectively a $150K income if we add in the median wage from the job you aren't doing.
