Sad thing is, it wasn't that way many years ago and yet it was still reliable back then!
Look, those WW1, WW2, and later.45s (up to the early 70s) were know to be reliable and well, just fair in accuracy. But they sure wern't 'precision devices'! Rattled like a can of BBs they did.
My Colt 1991 Govt. .45 is pretty reliable. Not Glock reliable, but pretty good. It cost me $500. I just added a Kings spade grip safety, trigger, and had a modest trigger job done. Now my Kimber Gold match shoots rings around it, but for CCW, I don't need that much accuracy (nor 1000+ dollar ccw guns!) I need reliablilty and just 'OK' accuracy. If it will hit a 12 oz coke can every time at 20 yards, slow fire, well that's plenty good in my book.
But why do I pack a Glock over the 1911? Weight is why. Weight and size.
Now like other have posted, the mico .45s arn't real reliable (and you have to change the springs out every 500 rounds or so). Plus those micro .45s KICK! So that leaves the steel 1911 or commander size guns. They are heavy and they are big (yes I know about the LW Commander, owned several.) Cooper was right, God intended for the 1911 to be a 5 inch barrel slegehammer.
Glocks are neather big nor heavy (at least the midsize and sub-compacts arn't.)
That and the reliability of the Glocks is what lead me to the dark side of polymer.
