You are running on the assumption that humans actually have any control over what they want.
True Unhealthy Truthseeker, but here's the thing. There are certain things that we can control and others that we can't.
Wants can be controlled to an extent. Now a want can be controlled not because you can will yourself not to want something, but because once you realize you want it, you can evaluate the possibilities and the pros and cons. People are a logical and thinking species. We understand that sometimes wants aren't what is best for us. (I'm excluding psychological problems, recreational drug use, etc.) A want can be negative and we can choose not to partake in the want. It is human nature to be curious and sometimes this can lead to problems. Essentially, a want cannot be controlled, but your decision can be controlled by you. So, yes we have control over our wants. Example:
We want a car. We have 500 dollars. We go and see a fantastic Ferrari, not 500 dollars. We see a used Gremlin, 500 dollars. We can see that we want the Ferrari, but we know that we cannot afford it and thus our decision is to buy the Gremlin for cash because it is cheaper and we are not economically able to achieve our want. We still want the Ferrari, but we know we cannot have it.
Another example:
We have some money. We want to buy a pool, but a relative has just fallen ill and needs money for surgery (mother, father, sibling, etc.). So, you can buy the pool (a want) or pay for the surgery (a need). We see here that we choose to pay for the surgery. Thus controlling our want for the time being. We understand that it is a necessity to save the life of our loved one. So we make the decision. Hence controlling our want.
Needs cannot be controlled necessarily. There are basic needs that are essential to the growth of a person both psychologically and physically that if neglected can have a negative effect. While a want is not a necessity and will have less of a long term negative effect on a person if they do not achieve it.
