Good, a tax on the uneducated, desperate, and mathematically illiterate is cruel and morally reprehensible to begin with. Propping it all up with publicity generated at the direct expense of the winners is pathetic.
What about those who are educated, successful and well versed in the mathematics of probability? They should be prevented from playing because you feel that some people should be protected from themselves?
Or do we now need an IQ test before certain types of activities can be enjoyed?
