Corporations around the world are using loopholes to evade paying corporation tax to governments. They are taking money from the community and keeping their contribution away the states.
My solution to the problem is very simple, I would publish a report of all public limited companies or corporations and compare their share prices to their tax contributions. I would then give them a fair trade score.
A fair trade score would work like this...If a company pretends to be struggling to the tax man then their shares should be very cheap, perhaps only £30 each. If a company pretends to just break even and sells their shares for £400 each, then you could give that company a low fair trade score because someone is being deceived either the consumer or the share holder or the tax centre.
The fair trade scores of each company could be published on an app and webpage that could be checked by consumers and influence where they spend their money. This would make fair trade a competitive incentive.
