Yes, it is a luxury to have the time to take a step back and consider your own society from a wider lens than "how can I beter secure my financial future this week." But without experiences like College, gap years, travel, and other "frivolities," you'll most likely end up as yet another short-sighted member of upper class who's spent a majority of their lifetime's creative power accumulating and hoarding wealth. Many don't have the bandwidth for both personal security and a strong social conscience, and I don't blame them for it...but I sure wish there were more with that ability.
Money is a very powerful tool and 18 is usually not old enough to be done with the formative experiences that will determine what you do with that power.
