Yes, "concise" essentially means brevity, delivering information with clarity in few words. It seems that you are asking for language that is accurate and/or comprehensive, not necessarily brief. So I thought I'd ask. Based on your response you seem to realize that you were in error, although I will go out on a limb and infer that you will never admit that.
@Angus Avagadro is a senior physician, so there isn't much concern about the education, and it's quite clear what he meant. I don't think any reasonable individual would infer from his statement that a doctor making 200K literally pays more dollars in taxes than a billionaire. It doesn't take much in the way of common sense to see that.
Also, nobody likes the Word Police. Have a good rest of your day.
