Just...what?
This is international trade we are talking about, not filling an expletive deleted pool! People who make and grow things overseas have workers, have mortgages, have profit margins, have transport costs, have employer costs - they have to ship their goods over seas and continents and they base how much they are going to make on orders from their customers and a reasonable stable price. That allows them to take on more workers if needed be, or even lay some off, sometimes difficult to replace. They have to invest in material and equipment and machinery and offices and trucks and pay taxes. They don't want to over invest or they'll go broke. And they don't want to under invest or they won't make a profit.
Trump, on a whim, has added tariffs, dropped them, increased them, raised them again, reduced them again...and this has been going on for months. Nobody, including Trump himself, knows what in blue blazes is going to happen next month, let alone next week. Ye gods, he could change his mind again today and sent out a tweet at 3:00am changing things yet again With some Letters Capitalised and lots of exclamation Points Into the Bargain!!!
It's a ship of fools and ol' Cap'n Trump is flicking switches and pulling levers and making announcements at random. There is no plan. He's making the whole thing up as he goes, because his poll figures aren't in the toilet any more. They have been well and truly flushed. And I swear, if he does another 180 and reintroduces the tariffs then you'll do exactly the same and say 'it's a great idea!'
This is incompetence on a scale I've never seen before in a modern western government. To say his fiscal policies are idiotic is an insult to idiots.
