Hey, if you actually believe our economic system can take a 3 year depression...go for it.
However, in that three years span, most construction companies would go out of business, as well as most chicken, cattle, and pork processors. The few that stayed alive would push prices through the roof. In turn, you probably would not be able to afford meat at the grocery store, which would raise the demand on soy products, grains, and vegetables, hence raising their prices. The middle class and below in America would be struggling to eat, and the next president would then probably institute tax rates of 60-90% (FDR?!?!) on the highest income brackets.
So, if that is your dream for America, then push it hard. Personally, I would rather have food on the table and put up the Spanish words on my American products as opposed to going hungry.
