Not inevitable. Souce code usually achieves 60%-90% compression with the hard-coded tables in use so far. But the table is biased toward source code and doesn't work so well with load modules.
There exists a formal proof that for any compression algorithm, there will be input resulting in larger output (i.e., you can't get something for nothing), but I'm too lazy and tired to track it down now. This is one reason why PKZIP, for example, supports more than one compression method.
