There are any number of criticisms I would happily join you in directing at the British parliamentaey system but I don't think relying on American businesses to pressure the government would actually be the win for democracy you seem to suggest?
For all it's issues, it's practically bad faith to argue that the UK is a democracy in the spirit of the term. I believe that's how the EU works with law?
Representives not representing their constituents makes democracy a sham. If you think representatives as of late are acting in good faith, I question yours.
