Is any of that OK? No. It's just not surprising.
What do you mean by "cost"? They both have to pay the same price, one might have to spend less time to make that amount if that's your point, but that's kinda obvious.
Hmm, I'd disagree.
$100K salary takes home $78K, i.e. $6,500/mo.
I don't know that a watch that costs nearly 3 months of every cent of my take home pay is "in the affordable range".
