What's interesting is that you don't realize how much of that stuff from Walmart had artistic processes embedded into it along the production line.
Did those shower curtains have a design? Did your sweater have a color and style? Probably so, but you never pay attention to how the world of "fine art" refracts into your daily life.
If the products were cheap, it's likely someone unpaid is responsible for the design. See, for example, the lawsuit against Zara over theft of ideas from small-time designers [1].
In any case, cheap Chinese brands do the same thing as Zara en masse (copying designs – note the "external suppliers" bit in its defense PR), and those products then end up in Walmart/on Amazon. The artists starve but you have your shower curtains and are happy with the price.

Even when people are paid, it’s not necessarily fair nor driving the price paid - like clothing/purse manufacturing in low income countries for high income markets.
Artists who were paid for by willing buyers, not tax payers who don't have a choice.
