Apart from the financial benefit that owners of business enjoy, they have no restrictions to move around whether within the work place. Like if you go to some business environment you see some information, out of ban for non staff" or non management, the owner isn't restricted in that.
Another aspect is that they are not restricted to go out to other functions they want to attend. They have freedom and liberty which is the most important for me. Working 8-5 daily is like a restriction of my freedom. And so I value that benefit and advantage of freedom for a business owner.
There are many advantages for business owners in running it, yes, among them they are free to come in at the working hours they want, whereas employees must obey certain times during working hours, and that is freedom for business owners and not constrained by time, I think that is the freedom that is obtained so that there will be a lot of time for business owners to expand their other businesses.
