He's not going to hire Magic+ for 40 hours per week.
Many services are $100/hr or more, they're just rarely billed out that way, because people have this reaction. If you have a moderate amount of disposable income, you can afford to have simple requests filled by Magic+ for $15-$30 (10-20 minutes of personal assistant time) several times a month.
The viability of the product for a solid middle class user really just depends on if Magic+ can fill the type of requests that you'd want to offload in a time-efficient manner or not. Some people in this thread say they're hyper-efficient and specially trained to do so, so it may be worth a try.
