If I were a con artist and owned a _______ company

If I were a con artist and owned a toilet paper company, I would buy out all the other toilet paper companies and then raise my prices super high. The demand would be very high, and I would be the only company left. As the only company, everyone would come to me, and with my prices SO high, I would make a mega ton of money. I mean, let's be honest, who wants to go without toilet paper? 

If I were a con artist and owned a gasoline company, I would just be a regular gas company owner. Oh, burn! 

If I were a con artist and owned a pet breeding company, I would stop owning that company because breeding is stupid. Then I would go work at the local humane society. 

If I were a con artist and owned a shoe company I would also be a foot surgeon. I would engineer all my shoes to be insanely stylish and comfortable AND CHEAP... at first. After a few weeks of wearing them, the shoes would severely mess up your feet and you would have to come have me do surgery on your feet. Shoe money + surgery money = lots of money. People would still buy my shoes even though they screw up your feet because they're so affordable and stylish.

 

If I were a con artist and owned a Christmas tree company, I would have fantastic tall and full trees. I would only sell my trees, however, to families with a member who has an unstable mental health past. I would spray all my trees with unscented hairspray (so nobody would know) and when families turned on the fireplace, their houses would catch on fire. This is a terrible thought, right? Burning people's houses down and blaming a mentally unstable person in their family? Wrong! I would also be a firefighter. Not a regular firefighter, though. I would just happen to be near when the fires start, so I would put out the fire and save all the people in the house! 
Tree money + reward money from the city for saving countless people = lots of money
Bam. 

If I were a con artist and owned a cell phone company, I would have really cheap phones and plans. That way, more people would buy my products. Then, I would arm the phones so that whenever they're on, they produce a nearly inaudible frequency that would make all my customers go completely insane. The only parallel between all these thousands of people going insane and ruining their lives would be their cell phone company, and that is a highly improbable parallel to be at fault, so I would never be blamed. 

Eventually, though, I'd probably be found out and get sent to jail. So I guess all of this planning is in vain.
