you need to read the post, by volume in a single country its Malaysia then Australia, UK and the USA which added are almost double the Malaysian count.
Language skills have died out here, the 60yrs and over can speak Malay English, family dialect and Mandarin as you would remember.
Under 20 good with English and Mandarin, 20 to 60 English and maybe one other.
Plenty cant speak with their grandparents as they need family dialect.
(Many older Indians can speak a Chinese dialect but not young ones.)
You love to dream about things rather than reality, perhaps what you think was all true 40 years ago, the gov of LKY did a great job but he also engineered the issues Singapore has today and the current gov is struggling to turn that around.
Too much time and resources spent staying in power rather than lifting the population up.
Lots of shiny infrastructure built by foreigners full of foreign companies and employees.
