I can break this down to a much smaller level. Chicago, the city itself, used to own its own parking meters. Some years back, in exchange for a billion dollar cash injection, our last mayor
sold rights to a private entity, LAZ parking, which is tied some some other corporations, leading if I recall correctly to the UAE. Well, Chicago was charging a dollar or less in most places, with
a bit more in downtown business district. The billion was used to pay off *some* of Chicago's debts.
LAZ parking got all the meters, and has been increasing the price ever since. Chicago foots the bill for the maintenance of the machines

and helps enforce the ticket issuances, though
thats LAZ getting paid off of those as well. Basically a "hero" swoops in, entrenches itself, and makes back the investment a hundred times over. We are stuck with this deal for 75 years. No bullshyt.
The Chinese build the infrastructure...then for maintenence "We can take care of that too, for XXX amount." You basically create a revenue stream that lasts for decades, and groom the population
to accept your presence. Thats not to say China will take anything over, but they will undoubtedly be sure to make sure Africa's economy becomes dependent on China's whims in the future.
If Africa's leaders are interested solely in the comeup, expect them to go in poor and come out rich, while Africans reap the least of the benefits of the projects. They will be token offerings.
All big nations do this to little guys. They fukk with em, and make them Dependant.
