New Reality Seeds

The main problem with this scenario is that, until well into the 20th century, Mexico's conservatives saw industrialization as a threat not an opportunity. If Kaiser Bill married a Mexican heiress, he would be fiercely determined to prevent anything like Mexican industrialization. Mexico would be used as a colony, a Mexican revolt, at least from Chiapas and the Quintana Roo would be nearly inevitable.

Also, as all of Central America to the northern border with Panama was part of Mexico in 1820, the Kaiser will want to take these all back. There would be several Americo-German wars.
