What is the effect of the Supreme Court ruling in favour of allowing a company to deduct certain expenses from its income tax bill?

I deduce the matter that concerns my brothers is the loophole in present laws which allows a corporation whose stock is owned equally by two principals to take deductions in certain years for accrued salaries payable, never incur actual expenses for such deductions, and then have the liabilities written off without any tax recognition because the item is treated as a capital contribution by the shareholders. If on a balancing of all factors, this method of corporate tax liability reduction is a loophole that should be plugged, then it should be done by legislative action, not by judicial fiat. The majority opinion seeks to remedy the supposed leak by attaching liability to the individuals involved by extending the dominion and control cases, represented by Helvering v. Horst, 311 U.S. 112, 61 S.Ct. 144, 85 L.Ed. 75 (1940).
