AW2518H, dead, stuck pixel problems

I bought this amazing Alienware monitor off Amazon, everything was fine except for the fact that it had 4 dead pixels. I return it and get a replacement, this new one had 2 stuck pixels and 1 dead pixel. Just got a new replacement today, 1 single dead pixel in the very center of my screen. This is a 500 dollar monitor yet it has dead pixels, so here are my questions:

1) Is it possible to get a monitor with no dead pixels?

2) Could it be that it being shipped from Amazon (all the traveling) cause these dead pixels to occur? So should I buy it from a physical store? (Like Best Buy)

3) Why is it that hard to make a 500 dollar monitor with dead pixels? People tell me how hard it is to make a perfect LCD monitor. So basically I am asking why dead pixels are so hard to avoid?

4) Are there companies that make perfect monitors or do most monitors from any company have dead pixels?

5) If dead pixels are so common, is there a way for manufacturers to change how they make the monitor to avoid the defects?

Again, I did not buy this from Dell directly so it is not their fault. I guess they are the ones making it though. I am just asking because every replacement I get has dead pixels or stuck ones combined with dead ones so I just want to ask anyone that has this monitor if theirs are "perfect" because at this point I am honestly thinking all monitors have dead pixels but people who have "perfect" ones just don't see them.
