Yes, I agree.
It's really annoying when there are some new bike configurations where the b-screw is just not long enough to do the job, due to an improperly spec'd/matched/designed(???) derailleur hanger. If the lip on the hanger is not close enough to the end of the b-screw (or, too far away, if you will), then it's possible that you are not going to be able to tweek out the clashing of the jockey wheel and the cassette.
It really amazes me that bike manufacturers can't get something so simple right. I've seen this on several occasions and, at first, I thought it was some problem specific to one bike, but then I saw the problem track consistently on every single bike of the same specific model.
Bikerjeg, you should take your bike back to the dealer and hold their feet to the fire until they fix the problem. Make them show you an identical bike and prove it's not something common to all bikes of that type. If they can't fix the problem with a longer screw, have them upgrade your derailleur. If that does not work, have them contact the bike manufacturer and see if they won't upgrade your model of bike. It's unfortunate that the shops get stuck in the middle on a deal like this, but the shops should definitely pass the problem right back to the bike manufacturer and make them fix it.
It would be wrong for me to name specific models that I know of, but I feel that a new bike customer should not have to put up with bad design, and that the manufacturers should do what they must to satisfy the customer. This is a really dumb problem that I've seen on numerous occasions in the last couple of years. In the end, it's just very poor engineering.
Edit: It's also possible that the incorrect derailleur hanger was sent with the new bike to begin with. Again, that's the fault of the bike manufacturer.
