~$12. Two estimation methods wound up around the same mark.
So, the same order of magnitude as spending $1000 on a dishwasher that lasts 10 years. Though of course in that case you also have increased water usage. And time taken to put things in the dishwasher and back on the shelves, versus time to get new disposable things out of their packaging. And space taken up by the dishwasher and your crockery shelves, versus space taken up by boxes of disposable crockery. Etc.
So, I dunno how these things balance out for anyone else, but to me it isn't clear that disposable dinnerware is a win even if we completely ignore ...
Two of the main resources people have are time and money. The world offers many opportunities to trade one for the other, at widely varying rates.
I've often heard people recommend trading money for time in the abstract, but this advice is rarely accompanied by specific recommendations on how to do so.
How do you use money to buy time or otherwise make your life better/easier?
