Question

Why is it a upper class and a middle class it ia not a such thing is is?

Answer 1

Now I wonder what your question would be if you wrote it in English.

If you mean in Europe before the industrial revolution....

The peasants produced food and lived mainly as subsistence farmers, eating what they grew, building homes by their own labour with locally available material.

The upper class were the landlords and rulers and responsible for winning wars and keeping kings on their thrones.

The middle class was small by today's standards but included the clergy and others who worked for salaries such as governesses and lawyers.
