I appreciate @tibfox but somewhere in todays date those companies are also lacking in some of the services to the public and those points i discussed was just to tell that if any common man targeted any of the areas i discussed and get an achievement to build those kind of alternates than really the life of that person can be really changed within a billionaire because those alternates are too hard to discover..But still possible to do so.. And i really appreciate and value your comment.. Thanks
