"Between 1824 and 1867 there were fifty-two presidents in Mexico, few of whom assumed power according to any constitutionally sanctioned procedure. The consequence of this unprecedented political instability for economic institutions and incentives should be obvious. Such instability led to highly insecure property rights. It also led to a severe weakening of the Mexican state, which now had little authority and little ability to raise taxes or provide public services. Indeed, even though Santa Ana was president in Mexico, large parts of the country were not under his control, which enabled the annexation of Texas by the United States. In addition, ... the motivation behind the Mexican declaration of independence was to protect the set of economic institutions developed during the colonial period, which had made Mexico, in the words of the great German explorer and geographer of Latin America Alexander von Humbolt, “the country of inequality.” These institutions, by basing the society on the exploitation of indigenous people and the creation of monopolies, blocked the economic incentives and initiatives of the great mass of the population. As the United States began to experience the Industrial Revolution in the first half of the nineteenth century, Mexico got poorer."
