Sorry, but that's not what this is about.
Of course, it's OK that kitchen studios make their margin...
Of course, it's OK that the kitchen is not manufactured in the Far East...
Of course, it's OK if people earn more than minimum wage...
It's simply about the lack of transparency: The example with buying a car is fitting here (applies to almost all other industries nowadays as well): One knows the exact value fairly well through online price exchanges etc. Going to a car dealership and buying a car at a completely overpriced price... that's almost impossible nowadays. The market is transparent, incredibly transparent. The same applies to electronic products etc.
With kitchens, this is not the case: exactly the same kitchen (same manufacturer, same appliances, everything identical) can cost between 10,000€ and 30,000€. It's like in a bazaar, and this is highly untypical for our culture here and does not correspond to the year 2017 at all... But this is how the kitchen industry wants it.
If I just go into one kitchen store and don't compare, then I can easily pay a 200% surcharge on the "actual" value. If I do the same at Saturn or MediaMarkt, such a thing is almost impossible (of course, it's usually a bit cheaper online, but that's not what this is about). And why is it like that? Because many kitchen studios try to fool the customer.
