I don't think you saw what I was getting at, here is a very explicit
example:
<cfset foo = CreateObject("component", "Salary")>
<cfset variables.salary = "123">
<cfoutput>#foo.getSalary()#</cfoutput>
getSalary will return 123
here is an even worse example:
foo.cfc:
<cfcomponent>
<cfset variables.x = "100">
<cffunction name="getX">
<cfreturn variables.x>
</cffunction>
<cffunction name="setX">
<cfargument name="x">
<cfset variables.x = arguments.x>
</cffunction>
</cfcomponent>
test.cfm:
<cfset foo1 = CreateObject("component", "foo")>
<cfset foo2 = CreateObject("component", "foo")>
<cfset foo1.setX(1)>
<cfset foo2.setX(2)>
<cfoutput>#foo1.getX()#</cfoutput>
take a wild guess what this outputs... 2!
not my idea of private.

The variable is private. However, when you use the getSalary method you
return a reference to the private variable. This is the same in Java if
you declare a variable as private and have a public "getter" that
returns a reference to it.
