There's difference between paying 19% of your income in UK vs paying 1% of your income somewhere in the Bahamas.

Over 90% of companies pay 19% of income tax + over 20% VAT tax. They often times coexist in the markets with the corporations paying 1%.

It's not important whether it's Google or Apple or BP - they should all pay the same taxes the small/medium business owners pay. Corporations use the same infrastructure that small/medium business owners pay for. Meanwhile they say "fuck you!" to said people and pay their 1% in the Bahamas. Additionally, they get enormous competetive advantage through lower taxes while medium or small companies need to gain it through superior products.
