Why those, who want a dictatorship, need an amendment? Create big depression with unemployment up to 30%
, then burn a reichstag
and voila, there will be a new "Constitution+", better than ever, no amendments needed... The key word, as it was already mentioned
is this thread, is - Crisis!
So, if you don't want that scenario to be repeated again by some "strongman", watch for government actions, leading to a "Crisis", or big depression, or (using contemporary words) "financial cliff"... Then make sure, that a fire department is always in place and ready to extinguish the potential fire.
By the way, they already have promised, that the first priority in the next year will be ... as you may guess, not the recovery from bad economy, but a new law (of course all for the children sake) to remove from public those "tools", that may help to extinguish the fire and to keep "strongmen" in place, where they belong...--
Keep it simple, it'll become complex by itself...
