Let's do not accept any paper to review for free. There is no difference between our time and expertise as a scientist with medical doctors, lawyers, psychologists, and so on. The academic publishers huge profit comes from our free labor. If one publishes an article in a newspaper, he/she will get paid. But it is not the case in academic world. Publishers even charge us to print our own work. If you want to change the academic publishing, just say No.
