Juneteenth is a joke. The USA is becoming like African Countries with up to 19 holidays and they are all insolvent. The lost tax revenue and interruption of production amounts to billions of dollars of losses without the American people knowing it and celebrates nothing.
Actually, what happens in America is the work that would be done today gets spread like peanut butter across the rest of the workdays. Many businesses remain open.
If you were right, economic statistics for the past 4 Junes would be down. I haven’t seen this indeed, the unemployment rate in 2023 improved.
