It is an important distinction. Contributions pay for employees, taxes pay for a successful society where companies can be successful. When companies end up not paying much tax, the feedback loop between successful companies and a successful society is broken. Society therefor no longer has an incentive, or even ability, to provide new opportunities for people. Instead you end up in a unsustainable situation where the incentive is to try and capture what is already there and not to creating new things.
