I'm going to use US examples in my post due to familiarity, but politically and economically US and UK are in similar crisis.
The London riots is definitely an example of opportunistic thugs. Gangs decided to take advantage of a peaceful protest to start looting. When police was ineffective, they got bolder and it spread all over. These are basically poor, uneducated, unskilled blue collar class people who have been hit hardest by recession and unemployment. However, that is no excuse for mindless violence and destruction. Many innocents needlessly suffered and the community will bear the brunt of the losses.
That being said I strongly believe the government and their policies are to blame. If the current policies continue, more and more people will be left jobless, unskilled, uneducated with nothing to do but get violent. Education and opportunities decrease gang violence. Lack of education and opportunities promote gang violence.
Welfare and education system is broken in both countries. Hardworking, honest individuals actually do not get the welfare and education opportunities they deserve. Scammers take a free ride on the system. In some places the welfare is so ridiculous that people actually sit jobless to collect welfare. In USA people collect food stamps on welfare and then sell it on FB for profits, using the money to buy TV, games etc. Actual hungry people and homeless people are left scraping at food pantries.
Left wing socialists want to ignore all this fraud and blindly expand the program because people are suffering unemployment and recession. Right wing conservatives want to end/cut back all the programs due to fraud and ignore the suffering people as collateral damage. Left wing socialists want to highly tax the rich to get the money. Right wing socialists try to shelter the rich from paying societal dues.
In my opinion both sides are nuts and acting childish. They need to grow up and find a solution together. The programs are necessary but broken and need to be fixed. Fix the existing programs then see if it needs to be expanded or shrunk.
Many people view welfare, food stamps, medicare, social security as 'entitlement' but in essence they are insurance programs. We pay the 'premiums' in the form of taxes in our paychecks. If we lose our jobs, get disabled, lose our homes due to unfortunate circumstances we collect 'insurance payments'. Just like the premium of a mansion is more than an ordinary house, richer people out to pay higher 'premiums' because their magnitude of loss and compensation in loss is higher.
Properly implemented welfare and education programs also serve society by reducing crime and producing competent skilled individuals to benefit the workforce and national GDP. Proper implementation is the key and that means first eliminating corruption and fraud at all levels – from the government officials planning these, to employees and agencies implementing these and to civilians who receive these benefits.
Instead of making these changes UK and US are both spending unnecessarily in war and cutting back valuable things like education. In our state the governor cut millions of dollars in schools crowding classrooms and cutting after school programs which saved lower income kids from street gangs. Accelerated education, special education is all being cut back. That means bright students don't get opportunities they deserve. Learning disabled students are forced to be societal liabilities due to lack of education. In the recent budget debacle they eliminated subsidized loans for graduate students. It is almost like saying MBA, MBBS, Law, PHD & research programs are worthless. Either quit studying or be prepared to be in debt for the rest of your life. Even undergraduate fees have gone up atrocious amounts over the past few years and many freshmen are faced with the choice – get educated or go bankrupt.
Maybe it is the Indian in me, but I value being educated very highly. I firmly believe that no country can progress and sustain progress without a well educated society. It is not just about being smart and excelling at things. Education exposes you to people, cultures, opportunities so that individuals are mature, well rounded, creative and hardworking. It gives people resources to tackle life's challenges. Without education you get dumb, unskilled, jobless people like the London rioters cant do shit in life but gang violence and robbery.
I hope all nations get a wake up call and bring back education programs, loans and grants at least and give more to schools.
