此句何意？get the 3rd degree because they decided to wear brown shoes instead of black.

Question

原文如下：I believe people have become tighter, meaner and less tolerant than ever. I never remember people being so uncool. I don't remember people getting the 3rd degree because they decided to wear brown shoes instead of black. If you get too close to someone on the road, they wanna get out and shoot you for possibly hitting their car. What's wrong with these people?
文中I don't remember people getting the 3rd degree because they decided to wear brown shoes instead of black作者想表达什么？
谢谢指教。

Answer 1

我并不认为人们获得第三学位是因为他们决定穿褐色的鞋以代替黑色的.(我想是指人们认为黑色会带来不好的运气,所以改变色彩以改变运气,心理暗示吧)

Answer 2

我只知道直译；我不认为人们得到第三届学位是因为他们决定穿棕色的鞋而不是黑色。
原文
我认为，人变得比以前更紧缩更不宽容。我从来不知到道人会变得那么不自信********如果你和一些人在路上走得太近，他们会想离开还会因为撞到他们的车而骂你。这些人怎么了
