Classic Case of a Monopoly

So I have a little brother that is twelve years old right now, a few years back when I was still under my parents roof my little brother went through the phase where became obsessed with making money. When it got to the point where he no longer could do household chores to make money he turned to my parents and asked for there advice. They told him how me and my other younger brother would always do lemonade stands during the summer to make some extra cash. My youngest brother and his friends got together and made a stand. They set out one day to figure out a good spot in the neighborhood to set up the stand. They found one particular street that had nearly all cars in the neighborhood driving past it. One thing you have to understand about my neighborhood is that it is actually three neighborhoods joined into one. This is like the mecca of soccer mom's and kids running around during the summer. So there really is a great potential to make some dough. After finding this street my little brother and his gang went back the next day to set up a stand but to find there was already a stand established on that very street. My little brother ended up setting his stand up anyways. The two stands ended up really hating each other and were eating away at each others profits. After a few weeks of this going on a kid from the other stand came by and asked if they wanted to join up to stop eating away at each others profits. My little brother and his gang decided to join with the other group(which really surprised me). It ended up being a really good decision because they raised the prices from ten cents a cup to twenty five cents a cup. Not only were they making more money but each kid did not have to work as much. Looking back on it now I find it really amusing how I witnessed a simplified version of a monopoly through my twelve year old brother and his annoying friends.
