Manufacturing costs have to be 1/10th, or less, of the selling price because there are additional costs associated with: advertising, marketing, research, development, prototyping, inventory, packaging, transportation, insurance, breakage, returns, etc. Also there has to be a profit margin.
This is one of the driving reasons why manufacturing is offshored, in order to minimize labor and manufacturing costs, so that the final selling price is reasonable and competitive.
