I am afraid that in many countries - not only North America, mentalities, beliefs, superstitions and standards did not evolve sufficiently, and those who have the power and the wealth will do everything to maintain their privileges.

The lower and - increasingly the middle classes - growing aware of the many ignored dark sides of human history, or blinded by fake and massive propaganda, are losing their faith in politics, economy, religions, morality, justice, legislation and leaders.
The system sounds fairer than a party (or multi-party) based system, as, in spite of former ideals and their defense of the groups and interests of larger parts of populations, which/whom they were expected to represent, they seem(ed) to miss their aims repeatedly, and, depending on leaders, teams, supporters, sponsors, trends, politics and economic situations, they evolve(d) and change(d), often with negative consequences.
Additionally, warfare, terrorism, organised crime, environmental depletion and plundering are still a major threat to all the world.
Yes, a consensus government might be a good idea, but like with many, more egalitarian programmes, they need to find suitable teams for every key and supporting function, open the dialogue, and aim at sustainable issues; additionally, there must be more control from neutral boards or commissions:

But interests vary and the powerful trade, elite or financial groups and parties will seek dominance at all cost, instead of switching to fairer practices.
Also religious and philosophical ideologies should review their interpretations of values, obedience and devotion, and put an end to intolerance, superstitions, extremism, stereotyping, discrimination, shaming, hate-mongering, prejudice, witch-hunts, etc., all the more that too many of their leaders and representatives were seldom showing the "good example".
Like in smallest groups or relationships, there will always be conflicting interests, frustations and disappointments, as nobody is perfect, if we refer, for instance, to teams, partnerships and relationships:
