Farage is popular because the left have failed, it is a phenomenon being played out across Europe.
It's not the left specifically that has failed> It's the neo-liberal economics, adopted by 1st world countries as 'orthodoxy',that has favoured the wealthy and lead to ever increasing inequality.
Where do 'revolutions' , whether initiated from the left or the right, succeed'? In countries where there is a huge gap between wealth and poverty. The disadvantaged being the most numerous, the sheer weight of the numbers of the disadvantaged can bring demagogues of left or right to power.
In this instance, the left has failed; only the right is promising relief. It could easily be the other way round.
