Tim, to quote U.... ""We love Trump, as long as he delivers as promised, we will continue to love Trump". Those are the facts." Exactly, "as long as he delivers." You sound like someone who will be among the first to jump off the Trump band wagon if the shit hits the fan and your economy goes south.
Are you angry with this developing 'inconvenient truth', or angry with the messanger?
The article is trying to explain.
It is not declaring facts. It is investigating and analyzing trends based upon developing conditions. It is trying to warn, alert.
The article is only predicting the ramifications of the choices being made in Washington. Any economist can verify the conditions developing. It doesn't take a rocket scientist, so to speak, to decipher the potential threats.
A wall, can be physical or it can be financial, as with tariffs. Tariffs are historically damaging to free trade. It turns into a tit for tat game. Each government is forced to counter another government's increasing tariff, (read taxes), upon another country's export products.
It is very harmful to international business models. Investors and businesses hate unpredictability because they can't predict 3-6-12-24 months ahead. There is no long range 'stability'. Farmers and Ranchers require the ability to predict the cost of feed, labor, storage, shipping costs, fuel needs, pesticides and fertilizer. Banks require the ability to predict lending rates and the ability of the borrowers to repay loans. If farmers and ranchers cannot predict, and bankers cannot predict, then the whole system can come crashing down. If farm equipment suppliers, John Deere, cannot reliably predict sale projections, then do they manufacture more or less? Do they retain workers, increase or decrease manpower? Will fuel prices go up with more demand?
This is how I interpret the article. Let us both hope and pray for stability. G.
