Hmmmm... I'm not sure I like the comparison, FOG. Former guide and hire and tour operator that I am.
Money's not everything. The pickings in the tour business are slim for the guides. It can become a lifestyle if you are prepared to do without the trappings of society and have no personal commitment such as children and loans to support, and are prepared and can afford) to move around the country or world following the weather.
You DO become the burro in terms of carrying a lot of stuff (physically and emotionally), and you have to have the personality to deal with minor matters that seem like major emergencies to many clients. Risk management is an important element that you need to grasp before embarking on a tour guiding career.
If you are good at it, you may be in demand, and make more money. But be aware, that there are only so many times you can see a dramatic piece of scenery or engage in an "experience" before you become blase about it.
