Even if they are not technically selling at a loss (I actually suspect that they are, but in any case), their opportunity for a particularly high profit margin is something that is priced in to their outlook when they are looking to invest and purchase assets. If all of a sudden they don't have as many marbles to play with, they either need to liquidate assets they currently have to the control of foreign owners and invest more strategically (greater chance of using these marbles in non-wealth creating opportunities) or don't invest at all and lose all of these opportunities in the future.

I can transfer my wealth to you either by just giving it to you, or I can transfer my wealth to you slowly over time by not being able to invest in wealth generation at the same rate as you while my base investments depreciate.
