"Professional" is sometimes used as a kind of class or sub-class division among labor in (at least) the US. Lawyers and doctors are definitely in it. Various other groups may be in depending on who's making the distinction, and others like to imagine they are in. They tend to be the sorts who have vacation homes somewhere nice, and have some specific skill usually requiring significant education, rather than broadly "business stuff" as a well-off manager with similar wealth might. So, well paid highly skilled labor. Imagine the stereotypical Asian immigrant middle-class parents and if there's a profession they'd be absolutely thrilled for their kid to go into, that's likely professional class. The happier these imaginary people are, the more solidly professional class it is.
