Where to find higher consulting rates?

Have any IT consultants here been on a project where you knew the bill rate was really high but you only got a tiny piece of it (like paid $60/hr and billed out around $200)? Does anyone know of a company that pays consultants well - like 70-80% or more of what they're getting?

Name
       DDIS - Digital Data Interchange Syntax / ISO ASN.1 (DDIS/ASN.1) files

Description
       DDIS/ASN.1 files conform to Digital's Digital Data Interchange Syntax.  DDIS conforms to syntaxes that can be defined within the specifica-
       tions of International Standards Organization Abstract Syntax Notation One (ISO ASN.1), but is not itself an  implementation  of  full  ISO
       ASN.1 syntax.

       DDIS/ASN.1 files conform to the DDIS/ASN.1 syntax.  The DDIS/ASN.1 syntax is itself used to define other syntaxes.  The following are among
       the syntaxes that are subsets of DDIS/ASN.1:

	      DDIF   Digital Document Interchange Format

	      DTIF   Digital Table Interchange Format

	      DOTS   Data Object Transport Syntax

       Files that conform to one of the DDIS/ASN.1 family of syntaxes are described as DDIS/ASN.1 files.  More specifically,  however,	the  files
       are typed according to a particular DDIS/ASN.1 syntax.  For example, a file that conforms to the DDIF syntax is a DDIF file, and is identi-
       fied by the command as a ddis/ddif file. The command includes the string ddis/ as a part of its output if a file belongs in the	DDIS  fam-
       ily.
