Why Do We Get Up So Late?

In the first Si'if in Shulchan Aruch the Michaber says the we must be "MiOrer HaShachar", we must wake up before dawn so we wake the dawn and it does not wake us.  Why do most people not wake up before dawn today as is written without dispute in Shulchan Aruch? 

The Mishna Brura says that if someone is weak by nature or if he knows that waking up early will cause him to fall asleep during davening then it is better for him to get the amount of sleep that he needs.  Since today the nature of the world has changed and most people do not wake before dawn, the Pischei Tshuvos says that based on this Mishna Brura, many Tzadikim and Yirei Shamayim do not wake up before dawn.  "Ein HaKadosh Baruch Hu Ba B'Trunia Im HaBriyos", Hashem does not look for excuses to pick on people.  However if someone does manage to arrange his schedule in accordance with the Shulchan Aruch, says the Pischei Tshuvos, Ashrei Lo V'Ashrei Chelko!
