If your five year old can't collect laundry from a laundry basket and bring it downstairs or tidy a baby's toys into a toy basket or sweep up leaves or empty a dishwasher then you need to encourage more independence because they're all easily achievable by an average five year old (and all things that my four year old does).
Our laundry all goes in one basket. It's too heavy for a 5 year old. I don't want a 5 year old going up and downstairs and bringing it down piecemeal (probably dropping bits on the way).
Tidying toys to the point of just throwing everything in a basket, is a "normal" job anyway - I assumed this was talking about a greater level of sorting out.
5 year old could do leaf sweeping but not the point that it would be good enough that an adult didn't finish the job up.
Our cupboards are too high for a 5 year old to reach, so they can't unload the dishwasher (and I wouldn't want them climbing on a step stool with breakables).
I don't have a 5 year old by the way, but my (much older) children had unloading the dishwasher, gardening, laundry on their "standard" jobs list from when they old enough to do them without adult supervision. And they tidied (generally, not just their own stuff, from the age when they could sit up and drop toys in a basket i.e. a few months old).
I think paying children for jobs that they can't really do properly, rather than encouraging them to help in a supported way so they can learn, and understand that these are things they have to learn to do for themselves, is a bad mindset to instill. Different to paying a much older child for a job that they can do independently (and that you might actually pay an adult to do for you).
