I’m not that far off from your views. I do think one party rule can be healthy if people practice self-discipline. That being said, our leaders haven’t shown any proclivity for that have they. I’m not convinced you’re right, but there is certainly recent evidence to back up your position.
Take a look at 219 and 222 to see what you think.
If done with restraint, one-party rule could be a great chance to accomplish wonderful things. But, that is hard to do needless to say.
