Maybe, but much of it is speculation and some of it isn't actually true.
1. You can be sure that Apple's not "giving you" anything at or below cost. They're in business to make money - and they make a lot of it.
Businesses sell things at a loss or at cost all the time for various reasons. You have a fundamental misunderstanding of the goals of modern businesses. For example Amazon is essentially a non-profit company.
Amazon has been in business to get market share, and expand their company for the last 10 years.
Likewise Apple knows that they will not continue selling MacBooks if they price themselves out of the market by charging too much for the rMBP, and they don't want to lose customers by not innovating, so they improved the cMBP and they charged a lower markup than the COST of the added improvements to them.
2. None of the upgrades on the rMBP cost less than the equivalent would cost you to do yourself on a uMBP, except the display.
That that is simply not true:
512GB Blade SSD rMBP Upgrade: $300
512GB 2.5" SSD cMBP Upgrade: $700
512GB Blade SSD Cost: $575 (internet price cheaper third party equivalent)
512GB 2.5" SSD Cost: $380 (internet price cheaper third party equivalent)
rMBP 512GB SSD Upgrade Markup: -48%
cMBP 512GB SSD Upgrade Markup: +84%
3. The statement about resale value seems pretty dubious to me, I'd like to see some facts on that.
So stating a newer more desirable machine has a better resale value seems dubious to you. That seems delusional, but I've owned several rMBP's and several cMBP's this last year and re-sold most of them by this point. The resale after a year on an upgraded rMBP was -15%, the resale on an upgraded cMBP was -30%.
4. The potato analogy is poor.

Your pointless criticism was poor.

Like I said, the rMBP is not overpriced when compared to the cMBP, it is underpriced because it is a better deal from multiple standpoints, and that's how Apple wants it because they are aggressivly selling the newer laptop.
