Edit: want I wanted to say is, that prices are arbitrary. They are a number on a label. As a customer you pick what suits you best. If you think Sennheiser or Apple is overpriced, buy something else. It is their decision to set a price, as it is your decision what to buy. You are also not an "evil" customer, if you don't buy their headphones.
You don't get what's evil because you're reacting to the environment you know, but you don't have to. Imagine a better environment where your options are not limited to "expensive headphones" or "less expensive headphones".
We're not living in a dream world. The conditions you set have consequences in how people behave. Not just individuals, but also companies.
What is “evil” to these posters is always “profit above the value of goods provided”. It doesn’t matter whatsoever that the (subjective) material and emotional situation of every happy sennheiser buyer, employee, and investor is better than before.
Sure. That's true though to different degrees for everybody participating in a market-based economy. You can call all of us "evil", but then the term loses most of its meaning.
Instead of justifying the status quo, I think we would all benefit if we retired the concept of an economy that incentivizes companies to act evil in order to succeed in it.
