labor is a small component through and through. Most of the money goes to paying off capital. You can dd up all the salaries all the way through and they won't amount to more than 25% of the total.
have you ever thought where return on investment/capital comes from?
You can hire 100 people to make 100,000 needles a day by hand tools or instead build a $200,000 plant that make 10 million needles a day with three guys operating the machines. In both cases the profit goes to the plant owner, while in the second the cost of labor will be less than 3% of the receipts.
