You're only looking at half of the equation here. Following your logic, if my time is worth $100/hr, I should be willing to pay $99/hr for a haircut. But reality is that a haircut isn't just worth some utility value based on time saved, it's worth the lowest amount where suppliers' willingness to provide it at a given quality and buyers' willingness to pay meet.

So while the $99/hr haircut might technically save me money/time, suppliers of haircuts are generally willing to give the same haircut for $30/hr. If one supplier tried to pin their prices to the growth of their customers' income, they would go out of business. That is because the value of the suppliers time isn't increasing at the same rate.

I'm mostly bald... I got tired of paying as much as I did for haircuts and now mostly just use a pair of clippers on myself, since my goal is to take off all of it. I've paid for more beard trims the past few years than haircuts, though I mostly do that myself too.

Note, I usually use clippers on myself about once a week. Sometimes I'll use a shaver to get a closer shave, but generally doesn't matter as I don't care if there's a little growth, which is noticeable unless I literally shave daily anyway... which I'm too lazy to do, and definitely not able to pay someone else to do.
