Sure there's lobbying involved. No major corporation can survive without lobbyists, because, as Google and Microsoft found out, if you don't go after the government they will come after you.
But just think how the markets have changed, and how many old corporations have gone under or been bought out by bigger companies. All of these happen at lightening speed compared to a generation ago, and the pressures from international competition is much greater than it ever was in the past. Keeping a company alive despite the endless needs of everybody else - consumers, customers, employees, government, suppliers, banks... takes as much art as skill.
Meanwhile, sweeping the floor after everybody goes home is still pretty much the same job as it ever was.
