If the guacamole industry went belly up, it’d be a great opportunity to get into some urban farming, where they take old warehouses and turn them into giant indoor grow houses. Start those up, around the country and start supplying all the tex-mex restaurants and cut the mexican’s out of that market, we’ll see some sh*t start happening.
I think there are more than a handful of products and industries that currently come out of Mexico, that could easily be done in the US.
A small import tariff is not going to make any industry or ag product go “belly up”.
