1)
Most americans do not like to cook. [2][3][4] (Really, this is VERY well researched. Americans are unwilling or unable to cook, due to a lack of desire, and a lack of sufficient time to plan and prepare a meal. It's cultural. Deal with it.)
2) Due to the above, many americans subsist on either fast food, or prepackaged products. The comprehension of what food "is", and how flavors interact with each other, is an essential part of cooking as an activity, which again, has been exhaustively shown to be not an appreciated activity by the general american public. This is why people add epic fucktonnes of cheese to their au gratin, when what they really need to add is a protein source and some salt, along with a little starch to gel the sauce, and enhance the flavor of the cheese that is already present.
3) Glad you agree. Sadly, at least here in flyoverland USA, when you mention "Cheese", the usual things people think of are "Kraft Singles" (which again, ARE NOT CHEESE), and "Cheddar." The number of times I have seen people try to make home-made pizza with shredded cheddar is astounding; Really, the people here (at least) have no fucking clue how to use cheese, or why you should use different kinds of cheese for different kinds of foods.
4) While Wisconsin is a part of the USA, not all Americans are from Wisconsin. In fact, most americans are not from Wisconsin. As such, your anectdote does not really help with the general statement that americans dont understand cheese. People in Wisconsin understand cheese; they have a culture for it. The rest of the US? Not so much.
I actually really enjoy cooking, and of my own volition, learned how to use different flavors, including cheese. I am an outlier. -- As demonstrated by the multitudinous studies that demonstrate that.
