What do you see in this Parisian street scene ?

First thing I see is the people passing by.
Each individual of those needs food,housing ,electricity ,running water and this is just the beginning.
They need clothes,perfumes,soap,shampoo ,shower gel and cleaning products.
Each one of them needs a bank account ,an internet connection ,a phone,a simcard for the phone, a computer …
They need software on the phones and the computers as well .
They also need all types of services : transportation , food , health .
How can I forgot health ? Hospitals ,clinics, doctors , medical hardware and software , medecine research ,labs , universities.
Now let’s look at the street in general :
There was a company that won a governement contract and was paid to pave and /or maintain the road .There are street lamps. They were made from metal and basic materials that were extracted then made by a company or two until it’s a lamp ,sold and transported to the governement .Then another company was paid to install those street lamps . Someone is also getting paid to maintain them.
This is still the tip of the financial Iceberg .
The cars passing by are a an economy on their own . The material they are made of , the manufacturing ,the marketing , the design ,the showrooms, the energy it uses . The energy needs to be extracted then distributed then sold to direct consumers ( the people).
Same for every truck , bike , motorcycle,bus and even the subway !
The buildings needed one day to be designed and built . We are talking about Paris so each building has maintenance companies taking care of it and always renewing it .Every resident of the building needs all types of services we can think of from furniture to food to a fridge to wi-fi . All the residents are also having different types of problems every single day .
There might be offices in those buildings too , belonging to the companies offering different products and services .Where they will have furniture,computers , printers, software to handle the operations , the finances , the hiring , the e-mailing itself . So many small details .
In the lower floors of the buildings , we can see restaurants ,pharmacies and other types of stores . Those restaurants are there to feed the people but need farmers farming lands and so many other products to become the restaurant plate .
Even the lights , the decorations, the designs , the tiles , all those things needed to be produced and pass by a a whole supply chain .
The idea is to look at things differently . Where is the demand ?
Where is the supply ?
What type of problems is a very small part of the world’s 7 billion people population having that I can solve?
Where I can fill the gap and offer a solution ?
Thank you for reading .
