I know it's conventional wisdom that the lottery is akin to a regressive tax, but is there actual empirical data to support this? I'm not disputing it--it makes intuitive sense, but conventional wisdom and intuition are frequently wrong.
A little bit of searching and I found this:
https://www.accuracy.org/release/1521-lotteries-a-regressive-tax/
"Although no government agency is willing to call the lottery a tax, it is nonetheless a source of implicit tax revenue. [However,] when subjected to the tests of sound tax policy, it fails... Extensive evidence shows lotteries are regressive, meaning the poor shoulder a disproportionate share of the tax burden. The lottery is not economically neutral: it distorts consumer spending by applying an unusually high tax rate to a particular product. It is a hidden tax, lacking transparency. Lotteries unnecessarily complicate the tax system. Lottery revenues do not always benefit the programs for which they are earmarked, and voters may feel deceived when they approve lotteries for education only to find that legislators shuffle funds and their states’ public education systems do not benefit significantly. Finally, the use of state-operated gambling monopolies to raise tax revenue poses serious policy questions about government accountability.”
The quote is from Alicia Hansen, from The Tax Foundation. The details of the evidence aren't presented, so it's not a primary source of empirical data. But at least it's something.
