Yes, we are. If the goods don't clear Customs quickly, businesses who use "just-in-time" inventory lose money. I was involved in a software project related to this and I learned a lot from the requirements meeting.
Customs doesn't have to check everything; its software does a good job of telling what's normal shipping and what isn't.
If the goods don't clear Customs quickly China goes belly up and can't afford those nukes they are planning for US! Businesses can buy American.
