This difference can likely be attributed to the fact that most remote workers are freelance, which means a client doesn’t pay for benefits like time off, health insurance, 401k, and so on.
It’s not only that though. If an employer doesn’t have to spend money on desk space, Internet bandwidth, and other on-site resources, they can put those extra funds towards paying remote workers.
Then again, these salaries might actually even themselves out when you look at this from the freelancer’s perspective.
Sure, remote designers might take home more money than their employed counterparts… But they have to pay for their own taxes, business software, payment processing fees, time off, and so on.
