No, it doesn’t! While you can make a solid living as a proofreader — perhaps up to six figures in some cases — there’s an upside limit to how much you can earn. The reason for that is simple: there’s a limit to how much value even the best proofreader in the world can bring to the table. At some point, the text is perfect, and no matter how skilled you are, you’re not going to make it any better. If you want a freelance opportunity with more upside, pair your proofreading with writing and editing — two fields in which the amount of value you can add is much higher.
