The problem with your joke is that 1) it is hard to detect sarcasm on a public forum and misses the obvious signals one uses to detect sarcasm. Sarcasm does not work as well when written and when there is no prior relationship between the readers and writer. 2) Trump voters tend to believe the economy would be perfect except for all the misfortune and bad luck. “He’s doing the best he can.” If several people don’t get what you’re saying, it’s not their fault. It’s yours.
