I am not QF, but I am sympathetic to and respectful of the lifestyle because I have several dear friends who are QF.
My QF friends are not as materialistic as most middle-class Americans. They do not believe that every child is entitled to his/her own bedroom, television, Ipod, Wii, a bulging closet of clothes/shoes in the latest fashions, etc. as well as dance, music, and gymnastics lessons ad nauseam.
Thus, they find that the Lord does indeed provide, just not in the manner that many Americans expect/demand.
