First, it's DELOREAN. Please spell it correctly.
Second, you clearly do not know the history of the Delorean Motor Company.
Third, you said, and I quote:
Case in point, you can "unsuccess" them. It happened to JDZ, and it can happen with Elon Musk, too... when big governments and Detroit put their minds to put down a formidable competitor. He didn't "go out of business". He was illegally framed and exonerated of all charges against him. But in the process, the bad press was enough to kill his company and his life. If Margaret Thatcher, Ronald Reagan and GM didn't conspire to disgrace JZD, he wouldn't have been forced to go out of business, and would likely still be a viable company today.
