No matter what the situation is, everything is based on Economics… whether supply, demand, subsidization. All these variables need to be considered by master minded individuals so they are considered when coming up with an action plan that actually works. If any variable is overseen, this will create a failure. If the failure doesn’t occur, then that variable was not required in the first place. Trials and Errors have to take place to make sure that the Solution to the Problem is an actual solution, and not going to create another problem where then that side effect has to be addressed. Even if it is a minor side effect, it still has to be addressed.
