In Ontario (Canada), Value Village[0] has been a staple of the working and lower-middle class for at least 15 to 20 years, and continues to be. I can afford new clothes more than I used to be able to, and I still choose to go there for some items. I regularly donate my old (still wearable) clothing to the CDA[1] or Value Village directly.
I wouldn't say no one.
