Well the profits they make are due to state granted privilege in the countries they sell in, otherwise there products would be much lower in price. The drop in profits would mean that such cost cutting excecises that in the long term are inefficient (such as workers not being treated as assets and needing to hire more people to cover the problems that stem from this) would play a significant role in building up production costs which the exchange value of the product would be much closer to.
What is your definition of profit?
I believe in cost-price economics which does allow for what some would call profit since subjective disutility of labour allows some time preference so isnt a product of exploitation, what we have today involves state backed oligarchies which involve coercion so are exploitative though the market system isnt in itself.
