How much do you value your favorite authors eating or having health insurance?
This is a serious question: just a few days ago I was suggesting that a friend, twenty published books over the last thirty years, books you may have read or heard of, start a Patreon so that he might, for the first time in his life, afford health insurance.
People working full-time in publishing might have health insurance but are working for well below market (by outside of tech standards, which are pretty embarrassing) in some of the most expensive cities on earth. And they can't just move, because then they'd get converted to contract and lose their health insurance.
This is not to shame you for buying used books---that's fine, there's no way I'd have the library I do without them, and I grew up groveling the library and used bookstores because that was all we could afford. Readers are readers. But---and I encounter this again and again---readers' perception of value in books is fundamentally misaligned with the actual economics of the book trade, to the detriment of both.
