I would define most at 50% or greater. So according to this we are barely half way there.
Part of is that the manufacturer buys outside produced parts and those parts may be 60& labor and that is incorporated in the materials category.
I used to do complex estimating on very large construction projects and as most of the buildings involved are 60% (average) subcontractor costs our labor totals never carried the labor of first or second tier specialty subcontractors or material supplies as a “Labor” item in the cost estimate. Only our direct labor and all the indirect costs were carried. Often the indirect costs of labor equal or exceed the paid labor amounts.
