I'm Swiss - in fact, I live just down the road from the U.N headquarters in Geneva.
I voted for adhesion to the UN, but that does not mean I like everything the U.N. does. They are an empire of bureaucrats. Most UN appointments (like ambassador to the UN) are prized because it is a nice high-profile job, with lots of nice perks (house in Geneva, no taxes, servants, cars with diplomatic plates) and very few responsibilities.
The specialized parts of the UN, like the World Health Organization, spend around 97% of their total budget in Geneva, supporting their own bureaucracy, perks, junkets, and fancy office buildings.
But that does not mean that with some serious reforms, the UN cannot become one of the greatest sources of benefit to the human race.
We can dream, can't we?
