I thought you were thinking of the government petallus, your posts never lack benevolence, I was just wanting a little more "meat". It is hard for even diplomacy to overcome prejudice, and often what is attributed to me, is a reflection of "themselves".
What you suggest you would do is in fact what is being done.Attempting to manipulate public opinion, (astroturfing).It has some success as is demonstrated by the disputes on universal benefits that have arisen here.
We have benefited from something, probably for vote catching purposes,that is costly and may be questioned by the next government. Who cares? Not the ones that introduced the benefit, they were well thought of , the onus falls on the next government who SAY they cannot afford it, and attempt to astroturf, to change the opinion of even those who get the benefit, in an attempt to reduce it, yet still get votes.This is where your divide and rule comes in I suspect, we have the magnanimous, who are themselves, desirous of certain benefits, but not all, willing to concede some to the detriment of those that need them all.
I appreciate that they have no malice in their suggestions, but they show a division that can be manipulated by the government, who given their head, would set up a department to operate a new system probably involving a "means test", that many deserving would avoid,and so lose their entitlement,and would result in the overall costs being considerably more than paying the benefit universally in the first place.
I have emphasised say because it is apparent that this is a lie. We have more than enough were we not to give money to countries that are more wealthy than ourselves, and to fund illegal wars, and as you say, "i'm sure there are other examples i could think of but" and here I divert, I'm going for a walk.
