How do you maximize a left skewed variable in a dataset?

I analyzed a dataset of tourist expenses for a country here: https://rpubs.com/lovepeacejoy404/tourist_spending_tanzania and I noticed that the variable total_cost (how much the tourist spent in total) is skewed left because tourists tend to spend as little as possible and then there are few who spend a lot. If I am interested in identifying which aspects of tourism are more profitable and in which it is worthwhile to invest, should I consider for the categorical variables the highest value of the median of total_cost or the highest value of the sum of total_cost?
