mechwira you sound like a salesman. Well, your concept of supply and demand is not flawed but your concept of perceptional mechanics are.
Most ppl are brainwashed by the sales, marketing and invisible hands. The invisible hands are everywhere and it created an artificial market all due to manipulation of human physiology. I wont say I want to educate, I would prefer to enlighten the others. The more ppl who are enlighten, the market will not be so inflated due to "perception". Perception of value has no value. It is subjective. If the buyer like the HDB/bike/car, he is willing to pay the sky.
That is how cooling measures works. Invisible hands can change anything they want, but if we resist, there is nothing the sellers can do but lower the price.
Everyone is in this rat race, those enthusiast must be damn rich while the others are not. If everyone thinks like you do, kuddos to the invisiblehand. They have successfully brainwash you.
