Actually, OP could have retired early with that income and number of years working. It's called reducing your living expenses.
You know absolutely nothing of OP's expenses, cost of living (can change dramatically depending on which part of the country you live in), number of children, possible medical issues, caring for elderly parents (contributing to them financially) ... and have not factored in that the 145K salary was not consistent for the 30 years, and 30 years ago was probably closer to 30K, perhaps averaging 75-100K over the years, not counting taxes, which would chew up a significant part of that. You have a real problem here making snap judgments while knowing almost nothing about OP's situation.
For all you know, OP could live in California, where decent homes cost a million dollars, have 12 children, 6 of whom are in college, and need automobiles, having to pay large medical bills that weren't covered by college, and paying for the care of parents who may need medical or nursing care. In other words, you know zilch and are making snap judgments.
