Havana had all of those things you name. Havana was then a modern, stylish and clean city. A capital of the Americas. It was a city of culture and energy. It was a city of business, tourism, architecture, pleasure and work. Havana had more cars than any European city at the time. Havana had infrastructure, Havana was connected to the world. In 1849, newly developed communication devices were demonstrated in Havana. Today such actions are oppressed and could lead to imprisonment. In 1900 the first international phone call was made from Key West to Havana. Today Cuba ranks lowest in the Americas in telephone/internet penetration. Pre 59 Havana was a city rich in musical talent. Antonio Machin, Perez Prado, Beny More, Cuban contradanza, danzon, mambo, cha cha cha, were hugely popular and influential in the development of genres such as jazz and tango. Pre 59 Havana was a flow and ebb of musicians between Havana and New Orleans.
What you truly want is poverty and stagnation to prevail. Havana is not a zoo for you silly tourist to enjoy. Havana is a city inhabited by people VERY tired of bad roads, crumbling buildings, lack of essential products such as eggs, toilet paper, pencils, and what not.
