Catch phrases and slogans sound nice. But they offer nothing of substance. At best they may be a bit persuasive at election time. It gets certain individuals elected on a populist ticket. But they deliver very little in return. 

Applying the adjective "Radical" in their vocabularly is simply deception. If they could not deliver on the normal version of socio economic tranformation (whatever that is supposed to mean) how is a radical version going to make any difference? It's just rhetoric in an attempt to sound more convincing.
