There are thousands of food stalls in Sg.
And many are operating conscientiously even during this difficult period .

If majority can make it, it means the biz is still viable,  albeit some maybe earning less.

Those that are finding it challenging must be selling their food at uncompetitive prices ,or unpalatable stuff.

Not profitable or viable just exit, and let others do it !

While what you said make some sense, I think it is important to acknowledge that there are different types of hawkers:

1) Those who sell great food, and charge at premium price.. This group most likely is not affected even during COVID
2) Those who sell ok food, managed to earn a living in pre-COVID days with office crowd

When everyone worked from home, it is the 2nd group who suffers.

Is it because their food is priced uncompetitively, or unpalatable stuff?? Probably no, because if that is the case, they would be gone before COVID days..

What happen is the customer base that they rely on suddenly disappear due to work from home.. Is that their fault, apparently not.. Maybe some might say they can slash price by x% to attract customers. But it is the same group of hawkers who have razor thin profit margin and can't afford to slash price..
