I’m used to satire but I think this could have been written in a smarter way. The way you came across, as you may have noticed due to all the reactions, was arrogant and selfish. Which was your intention and believable, but there was no humouristic element and there was no climax to the “joke” which resulted in just a really streched out “complaint” about money. That could have been perceived as real.
Well just my thoughts, anyways.
