Site indexing by Google

Getting your site indexed can be very frustrating at time. Some time they are crawled quickly and other times there are not. You may be wondering what's wrong when you know you have fixed all the problems that could exists. After much resubmission, your site is still at the first point of not being indexed. Why? I think Google tries to put it off especially if you monetize your site. Don't get me wrong now, I am not saying thats what they are doing I am wondering? Probably they don't want you to make money for them to pay. Sometimes you set your goals and its obstacles like these that hinder your performance and growth. How long will they take to index your site? This is a question that I would love someone to answer. All in all I'll wait and see the outcome.
