This is not a system where institutional changes have much chance of occurring, especially where “tradition” is involved.

Half of the voting population is against anything resembling reform or progress, and only “for” regressive draconian changes. The other half has such a broad difference of opinion on what should be addressed first that they waste their time squabbling about it even when they have control of the executive branch and both parts of the legislative branch. When they do make changes, they make so many compromises and concessions that the changes are effectively small.
