The OP article is very vague and sensationalist. Yes, there are many stresses facing us all. However, the most concerning problems in society (employment sector, wages etc). have developed under successive different governments for decades (they are not brand new problems in the making that have only appeared lately). While it's all fair and well having a go at the "fat well paid middle aged tory men" and that we should "actually revolt";
1. IMHO you're being pretty naive if you don't believe/realize that other parties like Lib Dem's are labour are also stuffed full of fat cats.
The more you start closing the gap concerning the actual differences separating our political parties (like how they actually operate VS what they proclaim on their respective tins etc), the closer you get to the truth about the actual state of politics in this country.
2. Start a revolt? How, pray tell? By voting for a different political party?
Go for it, but don't expect a revolution that way.
Tories are on their way out regardless, but don't expect radical change under a Labour leadership either. Labour governments build unviable welfare states, Tories weld great axes chopping up those plans- it cycles around a lot like that.
(Not that I'm saying that we should abandon our democracy), but with the way our political system is currently managed, the current system/cycle of politics does very little to encourage politicians to build long-term viable solutions or to take much personal accountability over their actions (it's an eternally self-perpetuating blame game).
Avocado's?
Just media tripe.
What you need to realize is that In EVERY generation that has been and gone so far, old and young alike have been pitted against young in VERY predictable trends (leading older people to feel like society is in an eternal state of decline and younger people to feel constantly patronized & misunderstood etc). Apart from shifting trash newspapers/generating clicks, such eternal pitting mostly serves the purpose of having us all against each others throats (while those who are really accountable, never as a consequence have to face any united angry mob against them).
It's like in the Roman times- the Romans realized that if you keep the barbarian tribes at each other throats by manipulating them against each other, then the barbarians will never stand a chance of uniting (or uniting for long enough) to ever pose any real threat to the Romans (except that in the 21st century, politicians & the media understand this very well and apply the same manipulative politics against the masses). To maintain control and to perpetuate a system that is selfishly favourable, leaders very much understand that to conquer & maintain power, you must keep those you wish to subjugate divided.
The best way you can start a revolution is to start uniting more with your fellow citizens (of all age groups!), realizing that there's not that much difference between you all, and that the things you ultimately all really want are not dissimilar at all (like a functional NHS, livable ages, better pension schemes, cheaper fuel, better quality food etc), if not identical. But the problem in achieving this end, is that most of us have been tempted and led by the nose into squabbling amongst ourselves, and so the system perpetuates (nothing ever really fundamentally changing for the better etc).
