That has never been the definition of the Midwest. If you want to go by the census definition, you are wrong.
If you approach if from a cultural or demographic standpoint, you are still wrong.
I would argue that the Midwest ends at the banks of the Mississippi river and maybe carries halfway into the western states. Past that it is a whole nother place.
Montana is mountain west or west. Always has been.
Just to clarify and add to what you said, equity shares are not stocks. The gov gets dividends and such, but it isn't stock that is bought and sold on wall street. It's all about profitability and not about speculation. If the company makes money, so does the gov. If it loses money, the gov loses money.
