US president Donald Trump – or “45” for those who hate seeing the names of the office and office-holder together – promised that his administration would be good for business, “the greatest jobs producer God ever created.”

Eschatologically speaking, the promise has proven prescient. But the profits are not being pocketed by the companies (including some in the US plastics industry) that quickly pressed PR from the jobs theme. Rather, the anti-Trump movement is producing very big business for purveyors of plastic privies.

Alone for last January’s Women’s March on Washington, 600 of the portable potties, which even come in glass-fibre reinforced high-tech guises, were placed strategically around the National Mall, the famous park between the Capitol and Lincoln Memorial. It wasn’t enough, so more were ordered for the next march.

The booming demand has understandably won the president new fans. As of May, a Washington toilet provider with the descriptive name of Gotta Go Now reported revenues 50% ahead of last year. At rental prices of USD 85-125 per privy, that’s a lot of filthy lucre. “Trump has been great for the portable potty industry,” Gotta Go owner Frederick Hill told the newspaper Washington Post. “That’s one good thing he’s doing.”

Now if the conservative trickle-down economics theory also proves true, boom times are surely also ahead for plastics producers and converters.
