Article 74:  “Reichsrat has the right to object to laws passed by the Reichstag.”

This right makes a lot of sense if you understand the political system of Germany.  Germany was formed in 1870 but before this, it was comprised of a lot of different, separate states.  When the country was formed, it was clear that some type of state-based system had to be put in place to make sure no state dominates another.  The Reichsrat was the institution that was created to have the voice of the different states be carried out.  So here, one can see how this right is important to humanity.  The Reichstag was the house that would carry out laws, kind of like the United States Congress.  But the states in the Reichsrat had a right to object to them.  So let us assume that Bavaria, one of the richer states of Germany, would start imposing some of their values on the rest of Germany.  This would create a kind of tyranny of one state, or region, over another.  So this is an important check and balance on the power of powerful and populated regions to ensure that the character of smaller ones remains in place.  Though with all honestly, I do not know how much of this is respected today, I know that in the United States, it is carried out quite well.  Most likely it is in Germany as well.  

Article 109:  “Noble titles form part of the name only; noble titles may not be granted anymore.”

This was a crucial difference between the old order and the Weimar Republic.  The old older was heavily based on titles; nobles had a very high place in society.  This was a system that was fundamentally unfair, as it was based on birth and not on meritocracy; essentially these were values from centuries ago.  The Weimar Republic proclaimed equality for everybody - men, women, rich, poor, noble, not noble.  One can see that the Weimar Republic did not totally abolish nobles - they still could be part of names.  This was probably a concession to the older order, who did not just want to get rid of everything they held so dear.  So noble names were able to stay in place.  The problem though is that the titles had no power; the noble names were just letters in a name, meaningless.  At this point, it’s clear that nobility is a staple from centuries ago.  I highly doubt any country respects nobility anymore, especially in the West.  Most likely, if a person would claim to be a noble, they would get made fun of.
