No, that's not the problem. Here is the problem. I make a widget. It costs me $10 US to manufacture. I go to the post office, and ship it to an address directly across the street. They charge $7. I go on AliExpress. I buy a similar widget, and ship it to the same address. The total cost, the item plus shipping, is $6. Let's break that down. Their cost of manufacturing is lower. Let's say it's free. Ok fine. Trans Pacific shipping is cheap. Let's say it's free. Ok fine. They still have to ship it via the post office from the port in Long Beach to the post office in New Jersey; again, let's say that's free. The post office then has to deliver out across the street. The post office charges me $7 to walk it it across the street. Why should the Chinese shipper only pay $6 for the same service?
