So there's no reason for it.
yes dear there is a reason. If demand for bananas is high at a certain price seller will raise the price for the reason of making more money.
Do you understand now???
- What I asked you was "what does it mean for supply and demand to meet at a price"?
You couldn't answer that, and refused to think about it, choosing to be condescending instead (I always can tell when you know you're outwitted - you call people 'dear').
I just showed you how it is possible for supply and demand not to meet.
Generally, the concept is that in a free market everyone who wants to buy and everyone who wants to sell walks away with what they want, and they get it by adjusting the price they are willing to accept.
The assumption is that people will always buy/sell at whatever price the market will bear. They will never walk away from a deal.
So if your employment argument is correct, you will work for a penny an hour if that is al that is offered.
We know that's not true. You have some price below which you will not work (a "reservation" price), which represents your "disutility" - the price below which something loses all usefulness for you, and you would rather not have it.
Prices are not, therefore, infinitely flexible, and it is very possible to have unemployment in a "free market".
