Airports, conducive to boosting trade and travel, are also a source of nuisance to their neighbours. The challenge has always been how to maximise airports' economic impact, while minimising the effects they have on the people living around them. But who should act as the impartial judge to balance contradicting interests in the case of a dispute?
The crisis showed that the pivotal role of the banking system, essential for the smooth running of our economy, comes at a cost. Although bankers were the ones taking hazardous risks, it was ordinary people footing the bill, when governments used tax money to prop up failing banks. It raised the question of whether banks were there to serve people or the other way around.
Valuable, even necessary. Companies often post workers abroad to fill service contracts in other EU countries. However, these postings can be far from an unadulterated blessing. The workers involved can be exploited and companies may try to avoid tax and social security contributions in host countries...
With the US reluctant to act and Russia only too keen to support Yanukovych, it falls to the EU to mediate and do all it can to promote a smooth transition and fair elections later in the year. Founded on the idea that fostering common interests helps to defuse conflicts, the EU has always favoured dialogue over the use of force.
Politics is about running a country, or at least trying to get into Government in order to run a country. That is why there is one question that really matters if you are voting in Scotland's independence referendum. Can the Scottish Government be trusted to run a country? Providing an answer is no easy task. You could argue that the SNP has been in power since 2007 and the country has not imploded, but you could claim that total implosion is unlikely as it is propped up by the UK Government. Either way, the unprecedented nature of the debate makes judging on track records a potentially perilous endeavour.
The European Union doesn't just have a British problem. The Eurobarometer shows that public opinion towards the EU was undermined across Europe by the financial crisis. The ratio of people feeling positive or negative about the EU was around three to one before the crisis but is now evenly balanced.
Market abuses like Libor helped to precipitate and exacerbate the economic crisis that has beset the world over the last few years. Yet, while the victims of this sort of fraud can be measured in millions and damages in billions, convictions remain only too rare and sentences are often lenient, considering the scale of the crimes.
It was a bold move that could have cost him his career. But when Olympic diver Tom Daley released a video announcing his relationship with a man, it was warmly welcomed by Brits. Celebrities lined up to offer their congratulations on Twitter, while many newspapers ran the news on their front pages, hailing his courage...
Let's not digress into white paper bashing though, plenty of others have excoriated it already. The point is that Scotland's monumental decision is on the horizon and too many crucial questions remain unanswered... The future of a nation cannot be decided on conjecture and supposition alone. We need answers.
Bailout countries have been on the Troika's leash now for nearly four years, but just how effective have its measures been. The Troika - composed of the European Commission, the European Central Bank and the International Monetary Fund - is tasked with getting economies back into shape by proscribing a diet of strict austerity and plenty of strenuous reform measures, but its methodology has been questioned since the start.
