Do you think the Harry Potter series is good enough to be considered a classic?

I think that the Harry Potter series is capable of becoming a classic.I mean,why not?It's author,JK Rowling,is the first billionaire author in the world.If she is capable of achieving that,i do not see why its impossible for her books to become a classic.We may look 30 years down the road and our children would be saying:"Harry Potter is such a fantastic book!"
Not only based on the fact that i said above,others have been saying that it is very interesting.JK Rowling has a fantastic style of writing that brings out the characters,making them come to life.Thus,people will come back for more.The only thing thats stopping me from purchasing the book is the price.It is ridiculous.I would rather wait a few months and the price would be much cheaper.I will not be so stupid as to buy it so early and lose so much money.
But back to the reflection.The fact that so many people purchase the book at this steep price proves that it is a good book.And thus i conclude that the Harry Potter series is good enough to be considered a classic.
