In Sweden broiler is common political term for a person that has their entire career and life within the same political party and many of that political party's suborganisations like for youth, religion, students, women, scouts etc.
They have lived their entire life in a fake world, made up of political strife between different factions and political scheming against opponents, often within the same organisation.
This is far from reality where the rest of us live, thus that is why I also mentioned professional career as well. When people get contact with reality usually they shed the most stupid ideas they have. And a professional career can even be a stronger antidote against "moronism" than a formal education.
The thing is that the "better system" is never a choice, you have the system you have and the system we (you) have now was never by choice either. "Constitution" is a series of compromises, historical events, traditions and fads.
Thus you have to look where you live a change things depending on that, a system that works in one country will fail in another and so on.
Specifically in Sweden I would revert some parts in the 1974 constitution to the 1809 constitution. The 1809 constitution favours separation of powers whereas the 1974 constitution favours popular sovereignty.
