Throughout Japan at the time, the samurai numbered 1.9 million. For comparison, this was more than 10 times the size of the French privileged class before the 1789 French Revolution. Moreover, the samurai in Japan were not merely the lords, but also their higher retainers—people who actually worked. With each samurai being paid fixed stipends, their upkeep presented a tremendous financial burden, which may have prompted the oligarchs to action.
To reform the military, the government instituted nationwide conscription in 1873, mandating that every male would serve for four years in the armed forces upon turning 21 years old, followed by three more years in the reserves. One of the primary differences between the samurai and peasant classes was the right to bear arms; this ancient privilege was suddenly extended to every male in the nation. Furthermore, samurai were no longer allowed to walk about town bearing a sword or weapon to show their status.
However, it is equally true that the majority of samurai were content despite having their status abolished. Many found employment in the government bureaucracy, which resembled an elite class in its own right. The samurai, being better educated than most of the population, became teachers, gun makers, government officials, and/or military officers. While the formal title of samurai was abolished, the elitist spirit that characterized the samurai class lived on.

Coal was needed for steamships and railroads. The growth of these sectors is shown below.
