UC:  Capitalism can be "fair" or it can be terribly unfair.  We know that every economic system ever tried has included the powerful taking advanatage of the weak.  Capitalism is no exception.  We've had our periods of unfettered capitalism and w/o exception they've resulted in a few being very, very rich and many being very, very poor.  Read a bit about the "Guilded Age" of American capitalism.  You use the term "coerce" in a very narrow fashion.  If people are poor and their families are starving, you don't need a gun to persuade them to work for a pittance.  Additionally, I'm not sure having tens of thousands of peasants move to the urban slums to work in sweatshops qualifies as "improving economic conditions for entire regions."  
"Self-imposed guilt"...in fact all guilt is self-imposed.  It is a reflection of our values.  We raise most of our own food..the rest we buy locally.  If I hire someone to help me do something, I pay $20/hour cash.  I do my best to treat people fairly. GC
