After the end of the whole Mall of America Tycoon there is a special clip that shows you how you could win in three easy steps. I'll explain them here because I have watched the preview at the end 100 times.
Step 1: don't build anything
Step 2: destroy everything and brake all the contracts
Step 3: Block all your doors when lots of people come inside so there is no way for anyone to leave.
Those are the 3 steps that will make you win the game in only 10 minutes.
