You don't "conserve wealth" by losing money paying higher labor costs than necessary.
Yes you do, Henery Ford proved that paying workers enough so that hey could buy what you produced generated demand and demand generates production and production generates wealth. Not rocket science, paying subsistence wages does not generate demand. The American miracle is the creation of an American middle class that fueled demand that was met by American industry. Yall free traders have destroyed American industry and the collaspe of the American middle class will shortly follow.
