Both the Labour Party and the Greens as well as the local Donald Trump want to ban foreigners from buying houses in New Zealand.
Seems to me that if you want to increase the supply of rental housing to reduced rents to poor families, you would want to encourage absentee landlords rather than first-time buyers. Is my logic wrong?
Watching a history of prohibition. Started in 1850s, at least half a century before safe drinking water was freely available such as through tap water.
Beer was much safer than drinking water until a good way into the 20th century. Initial temperance movement was against hard liquor but quickly was about abstinence.
