Hokaaayy...
"The person" who was prosecuted. One. How many people are fraudulently claiming compared to all the people who will be affected by this? In fact benefit fraud is extremely low, read what BreakingDad put.
As for the rest, if you want to talk about "entitlement" and "fair", you need to ask yourself some or all of the following questions. Others could no doubt add more.
Who earns most money? Where does it come from? Is the amount of money they are earning a fair price for their services, or whatever? Does it fairly represent the value of their services to society? Does everyone in society have an equal opportunity to earn good amounts of money? Is everyone born equal? Do we really live in a meritocracy? Do you want to? What merits do you want to see encouraged and rewarded? Which ones are being rewarded right now? Have you noticed pay is dropping (in the services it's dropping in figure terms, considering the skills required at each level compared to 20 years ago, never mind real terms) and that most work no longer pays?
"We all had our say in the last election"... have a look at issues such as voter turnout, engagement, representation. Most people, especially poor people, do not feel their interests are represented well. Do you truly believe we live in a democracy? What level of democracy? What is society for? Does it not have some responsibility to all of its citizens? Do you truly want this 'dog eat dog and the devil take the hindmost' world that is being created? Does it really represent your best interests, now and for always, in every circumstance?
"all this talk about cruelty is rubbish". People are dying on benefit sanctions. Dying, ffs. Benefits are the lowest amount of money that our society requires people to have in order to survive. And it is being taken away from our poorest and most vulnerable, those whose only crime has been to be born unhealthy, into the wrong families, or have accidents. The DWP know damn well that removing benefits in those circumstances causes extreme hardship. Effectively that means that the state is committing manslaughter, imo. Is that the world you feel comfortable living in? Is this the society you want?
Your point of view is simplistic in the extreme.
