Compression ratio - why lower it???

If you were building a full time pulling truck or dragracing truck, why would you lower the compression ratio of the engine?

Before you jump in and say...

to support lots of boost (100 psi +)
OR
to support high rpm (5000 rpm +)
OR
to support head gasket longevity
OR
so you have to use Ether to start it on a 80 degree day
OR
whatever else there is???

Try and add why exactly lower compression is needed to support your statement.
