Whats the psychology of the consumer you are after when dropship?

I am thinking a lot about dropshipping, it doesn't look like an online business model that offers any value to the consumer compared to other models like blogging or affiliate stores, blogging and affiliate stores guide, inform and solve the problems of the consumer so it makes sense to make money from them. You give something and take something.

Dropshipping looks like a model that exploits the weaknesses of the consumer, so what is the weaknesses that we truly exploit when dropshipping? is it impatience and unwillingness to research? ignorance? indifference for money? a fail sense of security? a patient consumer can go himself on aliexpress and buy the product and also make his research, its not like it takes much time, it takes less than 10 minutes to accomplish this, so you don't even offer time. Are these weaknesses so huge that we can even make so much money with them? just what is in the mind of these consumers?

Im trying to make some sense of this model, i really need to understand why someone makes so much money with it since it will improve me as a seller and give me the advantage i seek when i list products. I have done some business before and have encountered crazy consumers but even then everything made sense somehow. Last time i saw a guy who sold 500$ tvs at 900$ on his site and made tons of money, i just don't understand why all of this stuff works.
