By and large , hawkers are making profits. 
It's a matter of whether they are greedy or just contented, whether they want  to earn more or less.

The free market will determine how much they can charge. They did raise prices recently but peepur did not boycott.  This means the recent prices are what consumers can accept.

Supposing tomorrow all mee pok sellers start charging $10 a bowl, I am sure there will be a backlash.
