We don't need a cure for the common cold. We do need cures for plenty other diseases, cancer for example...but oh, we haven't cured it yet! That means it'll never happen, of course, following the same logic as, 'I haven't learned to ride a bike yet, so i never will'.

Trust me, i hate Rich Bastards inc. as much as anyone, but unfortunatly it they who are funding the medical research that is making progress into curing diseases such as cancer, which, may i remind you, we have a one in three chance of contracting during our lifetimes...
