I have several members of my family who can live quite fulfilling lives without personally squeezing either the avocados or the Charmin & have for decades. As my immediate family's delegated grocery shopper I can tell you that grabbing a bunch of bananas, a wedge of Parmesan & a carton of milk isn't nearly the spiritual experience for me as it seems to be for you. We're all different.

As for the people pulling my onions & vinegar off the shelf - 1st, they are not necessarily teenagers (though you might be surprised to find not all teens are cretins); 2nd, their employer isn't eager to absorb costs of complaints & lost customers for quality issues; & 3rd, they are more likely to be gathering items from my neighborhood Safeway or King Soopers than a dingy warehouse or sweatshop (those 2 are union, btw). 

A busy single mom, an arthritic grandma who doesn't drive, or someone recovering from cancer treatment who needs to avoid crowds have other needs than you. This helps them live well.
