Political economist Andrew Aeria has sent in this comment, which I think reveals how out of touch Najib is with the hard reality facing low-income families in the country:
First, petrol price increase. He said: Change your lifestyle.
Then, crime: Change your perception.
Now, laundry drying: Change your habit by buying a dryer or dry your laundry downstairs.
This guy has no inkling of the life of ordinary people. He was born with a silver spoon in his mouth and he has never known privation or hunger. So, when he talks, his ideas and suggestions are all in tune with his privileged world-view of his own creature comforts. Does he think everyone living in a high-rise can afford a laundry dryer?
