Unfortunate to say the least.
I believe u and I recall the times when we are all young, our parents and perhaps even teachers innoculate such words into us (and to date, I still hear some parents preaching this to their children!!)
Parent/Teacher: Nah! U see the person there sweeping the road ah boy? U know why?
Child: Dunno leh. Why?
Parent/Teacher: Its becos they never study alot! Next time if u never study, go and sweep roads loh!
Parent/Teacher: Must remember, next time must study high-high, and den take high-high pay. Den wun become roadsweeper....
Simple words no doubt, but it will affect the child unconsciously in their motivation to study. To the child who can't differentiate between Right & Wrong, the Logical & Illogical, the deeper/hidden reason behind words, the child would naturally work hard and end up grasping (and possibly passing on) the childish mentality & equation of:
Education = Easy Work = High Pay = White Collar = Class = Powerful Position = No subjucation to anyone
No Education = Hard Labour = Blue Collar = Low Class = Low Pay = Subjected to utter humiliation
High time parents kill this unconsicious equation once & for all and nip it in the bud before half of the future population ends up with this dumb equation.
