The familiar song of the NIMBY knows no borders. What an amazing statement. Younger people must be immiserated because older person has bills to pay. At least demographically speaking the young man in the video won't really need to wait 40 years to get an apartment above ground. Population of SK is believed to have peaked in 2020 and is now rapidly plunging, with total fertility now way below 1.0. They used to project peak population in 2035 but now they are projecting to lose 1 million by that year.
Edit: Sorry, the 1 million is according to the "medium" fertility projection but since reality is already far below the "low" scenario, the projection is for losing 3 million people by 2035.
