Honestly, running a successful business is not easy and when we fail, we can only realize the mistakes we have made. There are many reasons leading to the bankruptcy of a business, so it is never too much to absorb new things and listen to people's suggestions.
It has already happened to me when my family hosted relatives and went out to eat expecting the restaurant to offer delicious food, as it was used to do, but it was a fiasco and I immediately noticed the manager/owner wasn't there, rather only employees were operating the restaurant. Result: we aren't going to come back there again soon...
The same way you feel the reason for the bad food is because the real owner of the restaurant is not there, so also there are still some restaurant you will go to and discover the reason their food is bad is because the real owner of the restaurant, who also is the manager does not know how to cook, or how good food should taste like.
So running or managing a business in this context depends solely on the individual involved, their experience, level of exposure, their level of expertise at what they do , and also their zeal/willingness to do the job and do it well, whether they be the owner of the company or an employee does not really matter.
