There’s no black and white to these terms.

Suffice it to say, when a working class person, say, gets a DUI, it will literally ruin their life.

When a middle class person gets a DUI, it will ruin their year.

When you’re upper middle class, that DUI fucking sucks. But you got it. Family is still going on vacation. Christmas isn’t cancelled.

When an upper class person gets a DUI, it will inconvenience their evening, and maybe, just maybe, their public image. (gasp)
