"We" aren't labeling the citizens, they're doing so themselves. The default mode is that people are subject to unlimited personal liability for the harms they do to others. Society has chosen to make available a privilege of doing business in a limited-liability form (corporations, LLCs, LPs), but that privilege has strings attached. Don't like the strings? Then simply do business individually or as general partners — and accept the risk of unlimited personal liability.

(Also, the Seventh Amendment right to a jury trial applies to suits at common law; NLRB cases arise by statute, not common law, although SCOTUS has extended the jury right to so-called equivalents of common-law cases, which seems suspect.)
