only coming at it from a perspective of shareholder's personal non-share assets being exposed. Incorporation also shields the assets of the principals of a corporation. The principals of the corporation can pay themselves big fat salaries then walk away from liability.
It is VERY common for persons to accept investment money, form a corporation, pay themselves handsomely and then, either through incompetence or even sometimes intentionally, run the company into the ground then run off with the treasure leaving society(taxpayers) AND the shareholders holding the bag.
