I remember this argument from the days of old; so allow me to bring forward a piece of wisdom from that time.
It is not for you to decide whether the author's asking price is too much or too little. All you can do is decide whether it's too much or too little for you.
Let's turn the tables for a moment.
Let's say you've worked for hours (even days!) on something you intend to release. At the completion of that project, you've got not only the time you spent on writing it, but the time and effort that went into learning how to do it. You (the author) may decide you should be financially rewarded by whomever wishes to use the result of your time and effort.
Now, what if I told you that the price you put on your product is unfair or unacceptable?
What if you were in a superstore? Would you tell the cash registrar that the price on the item you've already picked up is too much, or would you realise the situation and either pay for it or put it back?
Note for future reference:
You don't have to like the price of something to respect what went into it. Be mindful, please.
