Many migrant workers in Singapore are the only breadwinners for their families back home in Bangladesh/India/Myanmar. One of the reasons the Singapore government has done extensive testing way beyond global standards is that many of these foreign workers are financially disincentivized to seek medical help the moment the first symptoms appear. The fact that Singapore's leader has publicly promised stable incomes for this affected group speaks volumes of the government.
As a fellow south east asian, I am deathly afraid of the under-reporting and testing in other ASEAN countries. Singapore. A 2017 statista study of migrant worker populations in South East Asia (https://www.statista.com/statistics/711513/asean-number-of-m...) shows that Malaysia and Thailand have much larger migrant worker populations than Singapore. Their living conditions are either on par or worse than the ones living in Singapore, yet there are apparently no Covid-19 clusters among migrant populations in other ASEAN countries. This is extremely alarming.
