I am not a political theorist, or even an expert in politics. However, I shall comment as little more than an outsider on these matters.
It occurs to me that politics in this country is fundamentally broken. New Labour stripped away any semblance of a right and a left. However, where New Labour succeeded was as an institution.
So the principle problem with right wing politics is the contempt that it appears to hold the electorate with. The outcome of right wing politics is logically to ensure a free market, however the means employed to get to this stage is to rely on fear and misinformation to coerce a public, viewed as fools, into submission. This can have the unexpected side effect of collapsing into totalitarianism when not balanced by democracy.
Conversely, left wing politics succeeds in that it does not view those who vote for it with contempt, but fails fundamentally as it has lost its moral compass. The foolish electorate, unfortunately, require morality to be spelled out. When a left wing government does this, it becomes right wing in that it will view its electorate as fools to be goaded but when it doesn't do this it can never succeed as no one will support a cause that has no morality.
