Or just introduce higher regulations, including the degree to which a corp can compete across different industries.

For example, I sometimes thing large corporations can beat out smaller competition purely because they have/can afford a large legal/patent dept, that smaller single-industry players do not.

There should also probably be more rules wrt competition - allowing private interests to control TLD/DNS, protocols, Operating systems/ecosystems, hardware specs/compliance, the EM spectrum and other common utilities/services has allowed an extreme bent towards monolithic companies - force theses large corps to spin off internal services!

> On the other hand companies that have a positive impact on the environment and the society should pay less.

Just have a carbon tax. Setup a general scheme for SMBs, and allow larger corps to setup their own if they can do it more efficiently (regulate that, of course).
