The poorer the country (not on average) the more demand there is for low-cost transit, that demand brings down the price of public transport tremendously because less public money is spend on other (more private) forms of transit. The 'problem' isn't only people loving cars it's also people being able to afford them. In general it also isn't the rich asking for public healthcare and education. The lack of public transport shows the power of the wealthy over the power of the masses.
