Actually your cost of living should be lower upon retirement. I read somewhere that you should plan on replacing 70-80% of your current income. Your house should be paid off and your daily living expenses should be lower. You will also be taxed at a lower rate when you are retired.
Basic economics is prices increase over time. In an ideal world your house should be paid off, but not everyone has that done before they retire. I plan on selling mine before retirement and downsizing but that's just me. I know a few that still retired with a mortgage and were more than fine. It's all in how you plan and prioritized your life.
My financial plan is to assume my pension and SS aren't there when I go. Sadly it probably will be true
