I don't know about the development over time, but it is certainly not the most developed Latin American country.
On the overall logistics performance sore you will find Chile, Peru , the Dominican Republic, Panama and El Salvador before Venezuela if I didn't miss any during a cursory glance. The infrastructure score alone is also not really the highest as all the mentioned countries seem to have a better score in that department than Venezuela as well.
None of that does however change that the people can't buy sufficient things for their daily needs and that the capital city is one of if not the most dangerous city in the world.
