Deregulation of the financial system over the last 35 years and tax preferences that benefit corporations and wealthy individuals have done much to increase the before-tax incomes of the top 1 percent. An army of tax accountants, many of them recruited from the IRS, has figured out how to push the envelope on tax avoidance for the big businesses and wealthy individuals that can afford their high-priced services. For these folks, tax accounting has been transformed from a service that makes sure that required taxes are paid to a profit center that manipulates the tax code to generate huge returns at the expense of the tax-paying public. Increasingly what we see in the United States is the growing importance of tax-payer financed capitalism.

There is no economic reason that the debt taken on by corporations should be treated differently in the tax code from the equity invested by shareholders, but it is. Corporations get to deduct the interest paid on debt from their earnings, thus reducing the corporate income tax they have to pay.

The tax code also provides an incentive for private equity firms, which plan to hold companies they acquire for their portfolios for just a few years, to load these companies with debt. In good times, this greatly increases the returns to investors. In poor economic conditions, this greatly increases the risk of financial distress and even bankruptcy, and imposes great costs on workers, creditors and communities. For investors with a time horizon measured in years and not decades, this is a risk worth taking for the promise of higher returns.

Tax preferences mean that income from owning stock is taxed at a far lower rate than income from working—a point made by Warren Buffet who famously pointed out that his secretary pays a higher tax rate than he does. The fiction that bonuses earned by partners in private equity and hedge fund firms is ‘carried interest’ that should be taxed at the lower rate on earnings from owning stock, rather than at the higher rate on ordinary income that ordinary workers and managers pay on their bonuses, boosts the income and wealth of these already wealthy economic players.

The use of aggressive tax avoidance schemes is rampant among big businesses and wealthy individuals. Setting up a subsidiary that lives in a file drawer in a tax haven and owns the company’s intellectual property and collects the royalties on it, or that owns the loans the company has made and collects the interest, allows financial institutions, pharmaceutical companies, and IT companies to park their profits outside the United States and defer taxes on this income indefinitely while waiting for a tax holiday to bring their profits home. Setting up so-called blocker corporations in offshore tax havens to launder taxable income for foreigners and pension funds, and turn it into nontaxable income is another favorite scheme.

Tax preferences and tax loop holes enrich the already wealthy and increase their incomes while starving the country of much needed tax revenue. The meaning of this rise in tax-payer financed capitalism is that the rest of us must either pay higher taxes or do without necessary services.
