On 5 June 2021, G-7 finance ministers in London from the United States, Britain, and other leading nations reached a landmark deal to pursue higher global taxation on multinational businesses such as Google, Apple, and Amazon. The Group of Seven (G-7) large advanced economies agreed to back a minimum global corporate rate of at least 15 percent and for companies to pay more tax in the markets where they sell goods and services. Many nations have struggled for years to agree on a way to raise more revenue from large multinationals such as Google, Amazon, and Facebook, which often book profits in jurisdictions where they pay little or no tax.

a) Critically discuss the justification for and against the implementation of a minimum global corporate tax rate. 

b) Reflect on the impact of the above implementation on your career.
