Hello Kninjanin, like a large majority of people, I am rather sceptic about promises and "great plans", as history taught us throughout human history that even the best intentions and programmes are paving the way to hell.
Many "big dreams" are not sustainable or do not please everybody, and radical changes are generating conflicts, as no system is perfect - and one of the main obstacles is human nature and the everlasting tendence to exaggerate or belittle.
