They can be. If a claimant attends an interview and conducts themselves in a manner they know will disqualify them for a job then it is dealt with as if they failed to turn up for the interview. I have grassed people up for this before. The problem about clothing is that they might not own a suit, or even shirt and tie. If they can reasonably explain that they do intend to be appropriately dressed if they get the job then this is fine. I would not like to discriminate against people just because they are below the breadline. I know of schools who, when people have turned up poorly dressed for interviews, put them in touch with local charities who can help on that side until the wage comes rolling in. It is a hand up, not a hand out.
Another reason is because the people used to the system don't want to work because they get it all on a plate. At my last place I had a person come for an interview in jeans and t-shirt and later found he was only there to show the job centre he was showing up for interviews to still get his benefits. Make it a stipulation that if you are perceived to be sabotaging your chances for work then the benefits get stopped.
The mines? You are kidding? Nationalisation of core services? Do you understand the relationship between growth in profits and growth in jobs? The mines were not profitable for many years. It is a very inefficient way of getting energy and the investment needed (from our taxes) is unlikely to see any payback in the near future. I think it was the Express who ran an article about this as an idea around 3 years ago and got most of the figures wrong. Nationalisation or energy companies would also take investment we don't have. You then also run into the problem we are having with the attitude to the banks we have large chunks in ... We want them to make a profit as this pays back the investment the state has made. The people who can do this want a wage (and perks) equivalent to what they would get in other banks ... And yet we moan about the wages they get. The same will happen in anything you nationalise. You have to pay the equivalent rates as they would get elsewhere ... Unless you add an extra bit to it ... Public service. The idea that you are doing a public service is no longer seen as a high priority, partly because it is not portrayed as something rewarding. In fact the same media will have a go at anything they can which promotes public service, unless they can jump on a bandwagon, or happily publish / show others knocking it too. It doesn't help when you have politicians from all side who do the same.
Fundamental changes are needed, and various institutions need to come back where possible. Drain the flooded coal mines, reopen the mines and you bring back thousands of jobs and a resource the country is in dire need of. Also have nationalised rail and public transport running along side the private firms, as well as energy and telecoms. Jobs opened up, more of a market for the government to claw back money, more tax paid into coffers, more people in jobs, better all round.
