A Gallup survey measuring the last fifteen years clearly shows Democrats favor higher taxes (on some Americans) compared with Republicans.
Even when it comes to Social Security taxes, the benefits accrue mostly to lower income Americans. While the amount of income subject to taxes is limited and therefore higher income Americans pay a lower percentage of total income, their benefit is based only on taxed earnings. In addition, the benefit formula generates a higher proportional benefit for lower income workers.
There is also this question. What will government do with more tax revenue? Will it be used to lower the deficit and national debt or will be used as an excuse to create new or expand social programs with no spending limits, but instead with unlimited and growing liabilities. We can’t even come to grips and sustain the major programs we have now.
