The reason for that hope is that gambling and gambling advertising, with the rise of online betting sites and smartphone apps, has started to become a fairly genuine social issue. With advertisements like this one (https://twitter.com/sportsbetcomau/status/863634984682233856) [note: Ben Johnson recently was found to be on PEDs], or advertisements blanketing one of the busiest train stations in the country, like the following (https://twitter.com/Doc_Samantha/status/786665869787078656). These companies are, anecdotally of course, targeting their advertisements to the youngest possible market, in the worst possible way. The pushiness of their advertisements are a 'joke' amongst my friends.
Widespread gambling is generally seen as harmful to a society. It would be nice if the USA didn't voluntarily allow its citizens to be taken advantage of for corporate profits, for once.
