I see a lot of people talking about the privatization of firefighting and the future. In this case there is a big difference between the two types of firefighting that is being talked about.
1. The first type of firefighting is your traditional city structure firefighting departments. These are the ones we see most of the time in the movies(Backdraft, Ladder 49). These are government funded by local and municipal taxes. They traditionally provided structure and medical services to a city. While the firefighting portion of these departments has stayed public the medical(ambulance) services have been heavily privatized for years. Due to the large migration we have seen of people wanting to live closer to nature, wildland Urban Interface firefighting has become a service that these traditional structure departments have stepped up to provide as they have expanded their boundaries to provide services to the ever increasing number of homes that have been built outside of the traditional city landscape.
2. Wildland firefighting has traditionally been paid for and managed by the Federal Government. Last I saw around 40% of wildland firefighting resources are privately owned. This includes fire engines, water tankers, showers, food caterers, hand crews(20 man crews that dig fire line in an attempt to contain the fire), tree fallers(loggers who are brought in to fall dangerous trees), air tankers, and helicopters. This particular part of firefighting has been privatized for 20+ years and the Federal government shows no signs of changing this trend anytime soon.
There is also a lot of talk of people leaving the structural "public" fire departments to go private. In my experience the trend is actually the opposite. Private firefighters are generally significantly underpaid compared to their government counterparts. When I was working for the Federal government 15 years ago, I was making a base wage of $15-$20 an hour, if I went out on a fire I got $2 an hour hazard pay for the entire day. If I went over 40 hours in a week I then was paid time and a half and anything over 80 was double time and a half. If I got sent out on a fire for a 14-21 day tour I would work 16 hour days for 14-21 days straight and just be raking in the money. My private crew counterparts were making somewhere between $7-$12 dollars an hour and were only getting time and a half over 40 hours.
