You will probably not become a millionaire unless you have no family, you never get laid off/let go, and your salary scales with inflation.

There are other considerations as well, including cost of living (most high salary jobs are in high-cost areas), liabilities (debt), and so forth. If you want to get rich (again, 7-figure range), this just doesn't seem like a good bet to make.

My personal slant on things is that even if you do become a millionaire, let's say in your 60s, who cares? The point is to get rich while you can still enjoy your money. There's no virtue in being buried with your treasure.
