Tax equality. This means that 100% of everyone's income is taxed for Social Security, not just middle class people (scrap the cap). It means that no matter the source of your income, it is all treated the same for tax purposes (no more calling a salary "carried interest" to change the tax rate on it, no more taxing dividends and capital gains at a different rate).
End the Oil Depletion Allowance (ODA), and any other oil industry tax benefits, and redirect the increased revenue to subsidize alternative energy (solar, wind, wave, etc.) The ODA made sense a century ago when it was a fledgling industry, but now the most profitable companies on earth are the major oil conglomerates. Direct our subsidy to the job creating industries of the future.
A Wall Street sales tax—taxing financial transactions. A modest set of taxes on trades of stock, bonds, and derivatives could raise a vast amount of money—quite possibly more than $1 trillion over a decade. Virtually all the money would come from Wall Street since most people will cut back their trading in proportion to the increase in costs. In addition, a tax would reduce speculation and possible lessen the volatility in financial markets.
Stop lowering taxes on the wealthy. To whom much is given, much is required. No more free rides for the so called "job creators." The people who pay the price of low taxes are the middle class and the poor. The poor pay higher taxes on living expenses through their rent payments and can claim no deduction for it.
Make Social Security Trust Fund inaccessible for any and all purposes other than for Social Security Pensions,disability and survivor benefits. Money in Social Security Trust Fund must be prohibited from being counted against the National debt; Neither Congress nor "the Fed" should should be able be to access these funds under any circumstance!
Heavy tax penalties for all American corporations that ship jobs outside the US. This would be usable as as an incentive to bring jobs that were originally performed here back and to stop "outsourcing" them so readily in the first place. In addition, this would add much needed revenue to the Budget coming from corporations who can more readily afford it than the rest of us.
Financial speculation tax. Very high tax on profits from sale of stocks owned less than 1 second. Tax rate decreases the longer investments are owned, eventually reaching 0% for investments that are owned a very long time (several years). Tax would be on top of income, capital gains, or other taxes and would apply to all relevant financial instruments including futures contracts, derivatives, and short sales.
