delete or hide a column in a list in SharePoint 2010

When you edit a column in SharePoint 2010 there should be a delete button at the base of the page. However, there are some columns such as "Title (linked to item with edit menu)" that I cannot seem to delete. I instead hid this item like so:

1. click in the list to make the ribbon navigation appear
2. go to the "List" subtab within the "List Tools" tab
3. click "Modify View"
4. uncheck "Display" checkboxes as desired
