It is thanks to the block of shares that your employees have guarantees in case your business develops, they will receive, for example, 2% of the net annual income of your enterprise! It encourages your employees to make your enterprise progress! If your employees do not have stocks, they have to believe that you will not deceive them and will pay 2% of your company's net annual income all your life (do you believe the first person you meet?). The absence of any guarantees reduces your key employees' interest in working on the development of your enterprise, which impedes its progress and increases the likelihood of bankruptcy, so I highly recommend that you start a business by creating a joint-stock community of the most useful and reliable people with whom you had to have business!
