people seem to always associate "concentrate on profit" with "being a dick"...the two are not mutually exclusive.
Making as much money as possible isn't inherently bad...it's all in how you go about it.
That is very true, but if "making profit" is a higher priority than "not being a dick", then they will be a dick if it increases profit. It's not that being a dick is required for profit, but if you are willing to do so you will get more.
In almost all situations, being just a little bit of a dick is far more profitable than not being.
The real question is how much of "being a dick" does it take before profit starts to decrease due to customer dissatisfaction? If making a profit is the top priority (which it is for most companies) they will be "dicks" as long as the money saved/gained outweighs the loss caused by dissatisfied customers, like if they can grow a crop they need for a product at a third of the cost by cutting down part of the Amazon, but it loses them a third of their customers. In that example profit is the top priority, but other companies would put the long-term well-being of the planet ahead of profit and so would use sustainable crops etc. What about the law - should it not come above profit? I'm sure we have all heard about companies that have done things illegally to cut costs and later been found out, be it evading taxes, using illegal labour, or simply not conforming to regulations.
Slavery might have been a bit of an extreme example, but it is within the realm of belief that it could happen if the company thought they could keep it hidden from the public. If profit is of the highest priority, then no ethical or legal concerns would override that beyond "How much profit would we lose if we are found out?". I wish it weren't the case, but many companies do this (for lesser things than slavery mind), which is why the rainforest is being destroyed, why millions around the world are paid 50c/hour for 28 hour days in a factory, why farmers who grow crops abroad get 0.1% of the sale cost for their goods and so on.
As you said, "it's all in how you go about it" - that really should be the priority, not the amount of profit made, or at the very least they should be equal, balancing concerns (make as much profit as possible AND be ethical/not a dick), which changes "make as much profit as possible" form the top priority to a top priority.
