I like how clear and concise your essay was. Topics like Apple and the food industry were great additions to your paper, as it shows a clear understanding of what the authors were attempting to outline in their respective books. You did say, however, that

When you look at the economy, everything is planned.

I disagree with this statement, as it is impossible for "everything" to be planned by a higher order. There are certainly human errors present, no matter how large an institution or entity can be. Sure, there is a degree of planning done by those with power, but I do not believe it is as much as people may think -- at least there is minimal evidence to suggest so. Regardless, your comments about the concept of "planning" are on point and you bring a good argument towards the necessity of knowledge in order to be a successful planner. An entrepreneur needs to think ahead, into the future, and take a bet on something they believe will work eventually. The only way someone can do that is if they have knowledge of concepts like human behavior, trends, etc...

Additionally, you mentioned,

The author goes on to say that if things progress as expected, there will be no new problems. Wrong. Problems still occur daily, especially in the economic world.

I agree with your point, although I do not think that is exactly what the author meant. Hayek was explaining how entrepreneurs solve problems and therefore can mitigate the amount of problems across time. He did not state that we would have absolutely zero problems in the future. Funny enough, the creation of solutions to problems can often cause other problems too. An example of this is medication for an illness. The medication can cure the illness with a high success rate, although can also cause negative side effects. Regardless of that, I am in agreement with you that there will never be "no problems" in the economy. Everything is based on the perception of the individual, therefore it is impossible to satisfy the desires of everyone simultaneously, because we are all unique. By selling a product or service, you can provide someone with value, while also making money to use to provide yourself with some form of value. Value is based on the perception of the individual, so everyone finds value in a verity of things.
