What produce does Michigan trade to other countries or other states?
Because the United States economy is tied with economies from all around the world and it's been like that for many, many years. The United States relies on imports from other countries; if other countries produce less, we get less, and our prices go up. We also rely heavily on other countries for our exports; if other countries buy less, we sell less, and make less money to invest in imports.
Although there are no hard statistics on this, the states with the most figure skaters (and some of the best) are California, the New England states, Texas, Minnesota, and Michigan. Although there are great skaters from across the United States, these areas seem to produce more high quality figure skaters than the other states, perhaps due to their cooler climates (New England, Michigan, Minnesota) or their large size (Texas, California).
