The flip side to your argument, DrOne, is that in mass market industries (computers, Sony, etc.) they are making much smaller margins. The parts cost of an 861 v4, at the small volumes they do, is probably in the $2k region. I paid in the neighborhood of $15K for it. I believe the cost to the dealer was in the $10K range. So, if my $2k parts is correct then they're making an obscene margin. It's considered fantastic to make a 30% margin on hardware today.
You're confusing margin with profit. I'd rather make a 10% profit margin on $100m of sales than a 90% profit margin on $1mn of sales.
However it's not just the parts that you need to factor in to calculate M's margin. You've completely ignored the cost of their R&D to make these products, as well as the cost of their facilities etc. When you do that I can assure you it will be a lot smaller than you're currently quoting.
