My question is, how many self-published authors are making a living from their self-published books right now?
How do you define "making a living"?
Because increasingly writers whether self-published or not in the U.S. need to either have a "day job" a spouse with a job, or retirement income, because of the high cost of health care etc. Self-employed people need to pay for their own health insurance, and a much large amount for social security etc. because if you're self-employed, you pay your part of social security and the employer's part.
