In australia, big corp donate a few thousand and give cushy "advisory role" jobs to politicians after they leave office in exchange for contracts to build, own and run private toll roads.

It has been proven many times it's cheaper for the government, and therefore tax payers, for the government to get a loan and build public highways themselves. yet, all new highways are private.

big corp get given the land for the roads and have builtin toll price increases. One company raises prices 4% every 6 months. According to google, that means the toll doubles every 9 years.

For me to drive 22km to the CBD via toll roads costs $25 one way, and I save 10 minutes most time of the day. In 10 years time, it will probably be around $40 one way.

big corp make a billion or two in profit every year.
