It would actually be making sure that private companies are following the constitution would it not?
Building a country on the foundations of free speech and liberty is a great idea, but I don't believe the founding fathers had Twitter and Instagram in mind when the drafted it. If they had known then what we know know, they probably would realize that the majority of Americans are expressing their version of free speech online and the companies that run the social media platforms have ultimate control over who is allowed and who is not allowed to voice their opinions. They can let only Liberals post data, while deleting the accounts of conservatives and vice versa.
I get that the constitution is important it plays a large role in the freedoms you have today, but at what point would you consider amending it to adapt to life in the 21st century?
How about when AI ensures more unemployment in America? Truck drivers, cab drivers, manufacturing, retail etc. are all going to get hit hard when HAL 9000 grows legs and takes their jobs. Would you support a universal basic income when unemployment hits 40%? Do you really think most Americans will voluntarily donate their money to help those people out when they're already at risk of losing their jobs too?
It's not hard to see where things are heading... if you change nothing and unwaveringly hold onto the constitution without allowing any kind of interpretation, would it not be causing more harm than good?
