Good and bad. I find it quite useful to purchase parts and goods directly from China at 1/10 the cost of buying the exact same Chinese made goods from a middleman for 10x more. Now if I was buying non-Chinese goods that would be a different issue of course. But such are not available, nor will changing shipping costs make these goods made in USA. Going forward we will be able to buy the exact same Chinese goods as before, but at much greater cost. However it will enrich middlemen whom we didn't need before. In any case this will mostly affect small shipments. Larger shipments than China Post air packets (let's say 2-20kg) currently are sent through services like DHL and SF Express. SF Express is able to handle mid size (>1kg) packages economically. They send a container load of Chinese goods to the US at which point they are broken out and dropped into the US postal service, paying full domestic rate at that point. Pulling out of this treaty will also affect our costs of shipping overseas. Granted we don't ship to China so much but we do ship other places. Also things like buying books from UK booksellers, and selling books to the UK, is feasible under this treaty. That will be less feasible. Prices will go up. Which has its advantages and disadvantages.
