The automated dishwasher in my kitchen relieves human dishwashing services to the tune of an hour or two per week. Minimum wage where I live is $14/hr. That is, on the low end, a little over $700 per year. Would I be on the hook for the $700 each year, minus the current operating costs of the dishwasher, in order to have it operational in my home?

And should the taxed value be a straight up calculation like that? Humans are quirky and unreliable, and I may not be comfortable with having a stranger in my house to clean up after me. As such, I may be willing to pay quite a bit more to have the reliable and comfortable automation over hiring a human. Would the tax need to account for that disparity to allow humans to still have a competitive edge?
