Scarcity of people who can create websites and computer programs as compared to the demand for that vs the lack of scarcity of people capable to make T-shirts vs the demand for makers of T-shirts.

This is in large part driven by most website development being semi or entirely custom. (People who use Shopify to make storefronts or Facebook to make company landing pages don’t make the same amount as Shopify or Facebook devs.)

It seems to me that much like remote workers often get location-based pay which is lower than that for someone for doing the same work in a location like San Francisco or NYC, it's less that there is oversupply of t-shirt makers, and more that the pay rates of their local market are lower overall which puts them in a weaker bargaining position.

And when you start looking at why that is you get pretty awkward answers like: because of selectively enforced free market ideals where capital is free to move across borders but labour isn't. Which are ultimately backed up by military power.
