Without mentioning any political party, I can point out one thing that is clearly a problem and will prevent our country from going forward; the constitution.
Want to make electoral reforms? Let's open the constitution and see if every provinces agrees.
Want to change how anything works in the country, let's open the constitution and see if all the provinces agree.
Every time we tried to fix that, the country nearly imploded. It's a ticking bomb that we just ignore. We sweep that constitutional impasse under the rug every election, and 'everything is fine'.
