Legislation, Boycotts and Real Change
Legislation and boycotts seem unlikely to change massive corporate tax evasion just because not enough people actually understand and care about how damaging this behaviour is to the UK and other exploited countries.
To make a difference we need government and some socially responsible companies to start using initiatives such as #FairTaxMark and #BuySmart to brag about the fact that they pay tax and are proud of it e.g. "we need our UK people, roads, security, schools, health to run our business AND we actually help to pay for it".
Eventually, when faced with an easy choice, for instance, between Starbucks and Costa, more people might start to think twice before handing their cash to the greedy corporates who do so much hidden damage to the societies that support them.
