Why don't people indent C++ access specifiers/case statements?

Question

I often see stuff like this:

class SomeClass {
public:
    void someMethod();
private:
    int someMember;
};

This seems totally unnatural

Answer 1

It's all about scoping and grouping of branches. If these are not affected, then do not add an indentation level.

Take for instance the following:

if( test == 1 ) {
    action1( );
} else if( test == 2 ) {
    action2( );
} else {
    action3( );
}

Take note of the levels of the statement blocks. Now re-write it as a case statement with indented cases:

switch( test ) {
    case 1:
        action1( );
        break;
    case 2:
        action2( );
        break;
    default:
        action3( );
        break;
}

This does the exact same functionally, yet the indentations don't match of my actions. And I think it is this inconsistency that finally made me change to dropping the extra spurious indentation. (Even though I don't mind the half-indenting proposed by others, mind you.)
