That is not what is happening in Switzerland. There isn't reallya reason why ot would play out differently in the USA.

The beginning might be turbulent, but that should cha.ge after a few years

I would guess the Swiss population is generally more educated on average compared to the American public, which to be fair is easier to achieve with a population of 9M vs 328M. A sufficiently educated public is a requirement for a more direct democracy to have desirable results.

America really needs an education system overhaul, teachers are often paid close to fast food restaurant staff levels of wages.

If you have a working education system, it will work exactly the same for 9 and for 300 million people. Its not about size but about the approach.
