— President John F. Kennedy, 1963

Myopic egalitarianism on taxes would have ruinous affects on all levels of society. The incentive structures that determine how we allocate capital determine how dynamic our economy is and thus the opportunities for working and middle-class Americans. Lower capital gains taxes encourages skilled investors to reallocate capital to promising projects, ensuring capital goes to the companies most likely to create jobs as they innovate and scale. Better investment of capital literally results in higher wages, superior goods, and a more sustainable tax base. The maximum capital gains tax in the US is already one of the highest in the developed world. It should be zero, like Singapore, Hong Kong, and a dozen other OECD countries.

Taxing capital gains as ordinary income would freeze long term investments in place. This is the “lock-in effect.” When capital gains taxes are high, the tax penalty discourages investors from moving their money to potentially better investments.

Obama said raising capital gains taxes was “fair.” However, that sounds good to voters that don’t know any better while it would be disastrous in practice. His statement was catnip to the economically ignorant just like “build the wall” is catnip to the right-wing. Both ideas are of questionable benefit while the potential for unintended consequences are somewhat infinite. Of course there are those that actually want the US economy to get worse in order to bolster anti-capitalist arguments. So perhaps the negative effects of taxing capital gains as ordinary income is a desirable outcome for those who suggest it. A bit cynical, however, how else could it be explained: if raising capital gains taxes is bad for the economy as Kennedy and economists say, why would anyone support it? They’re either badly informed or perfectly informed and malicious.
