Switzerland taxes imports with 8.1%;
good, but rather basic and neither luxury nor much compared to the United Kingdom, which taxes imports with a rock-solid 20% and so makes luxury really luxurious;
just the European Union creates even a tick more luxury for its citizens with a slightly higher tax-rate of 21% for imports;
and so the United States new general tax rate for imports (aka tariffs) of 10% could not be a surprise and is in quite good company; just with the planned increase to 31% it would become undisputed leader of the free and western world again: products that left the sellers warehouse as a normal good at a market-price arrive at the buyers door price-inflated to an unaffordable luxury item -- Adam Smith' "invisible hand" at work; never before luxury was more luxurious.
Ad 20250416: It is quite clear that I can absolutely understand the action of the USA, now. If all others close their market (agriculture, cars, pharma etc) or open it just after payment of an entrance-fee (tariffs, fees, VAT... you name it), then it is logical and reciproke to do just the same. This is happening now and the result will not be bad for all;
