I never proposed that the Constitution should be easier to change. For the past 30 years, there have been no changes to the constitution. In the 1900’s, there were 11 amendments. That’s an average of 9 years per change. I refuse to believe that in the last 31 years, there was nothing important that 75% of States could agree on. The world has changed a lot in that time because of the internet and other technology. There’s definitely a lot of new things that there could be amendments about.
You say you never said the Constitution should be easier to change then complain it hasn't changed. Spend the rest of your wall of text saying it should have changed.
An example would be an amendment on privacy and data collection. Over 80% of americans feel very little or no control over data that is collected about them. 81% feel the risks of companies collecting data about them outweigh the benefits. Source of data: pew research.
The government is already supposed to be limited per the constitution. We have in there the right to not be unreasonably searched and seized. We just need a court to intervene one day. As for private companies encryption is helping, people are becoming privacy minded and existing monopoly laws should be breaking up other scenarios where it's hard. Like app store issues.
That said, I would like amendments that give us the right to refuse medication and not be treated differently in the workplace. The right to refuse vaccines without threat of being fired. As well as more privacy rights but it needs to go through the legal system.
I also wish they could have put something in there to weaken commercial interest in law making but companies were not able to grow as large as they have today because there were no computers to make book keeping easy enough.
