Like this pandemic has made, there are many jobs that are not pandemic proof and what if there's a worse scenario that comes that shall affect majority of the jobs.
Starting and running a business is not an easy task. There are some persons that would never dare to take the risk of investing or establishing a business. If everybody becomes self-employed who would be the employees that would carryout the daily task of these businesses. People that have intention to start their businesses in future can work in a firm with the aim of understudying how such business operates. This can help them to start and operate their own businesses. Others that are not skillful in running their personal business should ensure they invest wisely, so that when they retire they can have some funds or income to fall back on.
