It’s called negotiating from strength. The first rule is you always have to be ready to walk away right up until the deal is done. Just like Reagan let the Russians walk away from the START talks, and they ended up crawling back. Then Reagan walked away at Reykjavik. If you read the Art of the Deal you would know that.
My father told me if you go to a car lot and they arent kicking you out,telling you to never come back, you didnt get the best deal.
Granted that Trump is the best business person ever, ever. If so, will he also be maximizing profits? That is what businesses are after, after all, wouldn’t you agree? Do you think Trump would not want to maximize his profits? What is wrong with that, right?
