California doesn't pay taxes though, people in California do.
Not trying to be pedantic but this is a common framing that is, at its core, completely incorrect. States don't subsidize states because taxes aren't earmarked based on what state they came out of, it's all just government reallocation of wealth by one means or another.
Even if you were to accept this framing, California's net contribution does not cover the shortfall from 26 states, so the statement would be wrong even if it wasn't deceptive.
