Query: Horrible Quality Control & Bad Materials

I have a pair I bought and the belt loops are coming off. On the leg inseam they stitched down one side and didn't even bother on the other side of the seam. Yes. There is a thread looped and hanging in the air. I leave it because I don't want one half of my pants leg to unravel. Quality control has gone to hell since Levi's very unwisely moved their sewing to South America. Hey Levi's if this is what you want to produce: shoddy, lightweight, crappy quality control junk then more power to you but you have seen the LAST of my dollars. Enjoy South America. Maybe someone there will buy the overpriced utter junk you are producing these days. What a tragedy.
