I don't know that it is essential for an employer to learn Excel. The owner of a business may well hire someone who knows how to use Excel to provide him/her with the data for the business.
Here is my point of view:
Everything that was said is applicable to a small business, or a small department where the data is of limited size.
When the enterprise grows in size, or where the customer base is extensive, Excel simply cannot handle the growth. It is not a scalable software like most other database applications. Even it's close cousin, Microsoft Access, has limitations when the size of data or complexity of the application grows beyond a certain level.
At the national or international level, databases need to be distributed, i.e. information needs to be stored at different locations but accessible to every user. Excel will not even come close to these requirements.
