Elon Musk tweeted about the possibility of Greece being the first country to suffer a really serious “demographic collapse.” "Greece is one of dozens of countries experiencing a demographic collapse due to low birth rates," the tycoon wrote in X as a quote from an article by The People's Voice TV. Demographic collapse is the phenomenon of depopulation linked to a sudden decrease in the number of people alive in a society.

The low birth rate, economic instability, women's unemployment and the lack of government efforts to promote fertility make Greece suffer even more from a situation that affects almost the entire European Union. The article cites voices of authority, such as those of the Minister of Finance and the Prime Minister of that country, while at the same time exposing a strongly anti-vaccine position by considering COVID-19 as a possible cause of the evil that Greece is suffering. The Washington Post attributed Greece's population decline to “the country's deep and prolonged crisis, which began in late 2009 and worsened in 2011 and subsequent years”
