Why America Should Spread The Wealth

Many economists worry that making societies more equal through income redistribution or other means lowers economic growth. This “big tradeoff” between equality and efficiency, which is supported by comparisons of capitalist and socialist countries, implies that there is a limit to how much redistribution a society should pursue. At some point the tradeoff of more equality for less output – which worsens as we push toward more and more equality – becomes intolerable. However, while the tradeoff is quite unfavorable as we push to extremes, recent experience suggests there is a wide region where the tradeoff is hard to detect. Thus, worries about this tradeoff appear to be overblown.

For example, the Bush tax cuts were justified, in part, by the claim that equity had overshadowed efficiency in tax policy decisions. Taxes on the wealthy and the inefficiencies that come with them were much too high, it was argued, and lowering taxes would cause output to go up enough to lift all boats substantially. Accordingly, the lower end of the income distribution would fare much better after income trickled down than it would under redistributive policy.

There’s little evidence
that the Bush tax cuts
had any effect at all.

The economy did grow after the Bush tax cuts, but the rate of growth was unremarkable, especially for jobs, and there’s little evidence that they caused large increases in output growth as promised. In fact, there’s little evidence that the Bush tax cuts had any effect at all. The tradeoff simply wasn’t there.

And the tax cuts at the upper end of the income distribution did nothing to correct for the fact that although worker productivity was rising, wages remained flat – a problem that began in the mid 1970s. This was an indication that something was amiss in the mechanism that distributes income to different members of society. Workers were helping to increase the size of the pie, but income did not trickle down as promised and their share of the pie was no larger than before.
