Marx’s great contradiction ?

Marx said that value was created by the labour power and materials put into a product. 

But wouldn’t that mean that his theory predicts that profits will be higher in labor-intensive industries than in capital-intensive industries, which would be contradicted by measured empirical data inherent in quantitative analysis. 

He did a poor job of explaining this contradiction in vol 3. 

Is there another way to approach this?

That is not a contradiction. Capital is accumulated past (dead) labour, and therefore the past labour that this capital represents is what gives that large part of the value not made by present labour in these “capital intensive” industries.
