We are so rich yet so miserable

Singapore is one of the richest countries in the world, or maybe the
richest on a per capita basis using the reserves divided by the
population of citizens. With this kind of money at the govt’s disposal,
why is it that the people are getting more and more unhappy and upset
with the govt? Shouldn’t the govt dish out some from the public coffers
to make the people happier and less miserable?
