Most countries have a feature, or features, that act as a national glue, to bind that country together.
Ideally, that feature should belong to all that country's people, and unify them, rather than divide them.
Examples of this could include the NHS, in the UK, the American constitution, in the USA, Islam in various Middle Eastern countries, or a national language in certain European countries.
I personally think these are very necessary, and once you start unravelling them, you don't really know where that might lead to. Nasty things can arise from those ashes.
BUT I also think that if criticism of them becomes a taboo, then they don't evolve, and will eventually cease to be national 'glue'.
I'll use the example of the National Health Service, in the UK, because that's one that is particularly familiar to me. This is free at point of access, to everybody, but is ultimately supported by the taxpayer. The work that the front-line staff do is indisputably outstanding, and it is a disgrace that many of these are working in sub-optimal conditions, without the appropriate protective clothing, for example.
However, our admiration for these front-line workers ought not to divert us from casting a very critical eye over other aspects of the NHS. Some chief executives of the NHS earn salaries of £250,000 or more, despite essentially being only the general manager of a single hospital. For comparison, the British Prime Minister earns approximately £150,000.
The NHS will frequently not pay small companies the break-even point for their products, because it can source similar products for less money abroad. In the current Coronavirus crisis, this has led to the supply chain disasters, which have been only too apparent in the news. You don't want to become dependent upon China for key medical supplies.
I believe it would be wrong, if the heroism of individual frontline doctors, nurses, porters etc were used to shield the mismanagement of the NHS from further investigation, when this crisis is over.
But that's a discussion for another day - which features does your country have, that are seen as above criticism, and do you think this is right?
