I'm sorry, this is a bit dumb. The senate was not founded because "we cannot trust the people" but because in the senate EACH STATE has equal power, regardless of size, while in the congress each state has power proportinal to the population. This ensures that small states with 0.2% of the population are not entirely ignored in all politial matters because they might literally have the ability to break ties, no more. It might wind up being that ruling NY + NJ + FL + TX + CA would give you enough power to outvote every single other state.

The senate is critical and not to be abolished.
