Really? Say you're working for a company that has a great year, profits up 50%. Your boss gets a 20% raise. You and your team get coupons for free fries at McDonald's. As your boss hands out the coupons, he assures you that profit is a good thing, even if it helps management more than workers.
I'm not sure what you're trying to say - that because some "undeserving" people will get more as well, nothing should change?
No, I'm pointing out that the wealthy take a bigger cut of economic growth not because they contributed more, but simply because they are in a position of power to do so. We can't leave capitalism unregulated and expect a meritocracy to emerge spontaneously.
Wealth inequality leads to inequality of dignity as it's directly tied to power balance among those unequal individuals.
