Corporations are not the same as People and The Citizens United SCOTUS decision was the most slippery slope there. And if you want to Weather some really serious social strife not seen since the last Gilded age then just go right back to the late 19th century and early 20th and look at Labor History in the US.

I do not see what this has to do with Small Farmers any more that any other business and really if you like depressions then just keep moving more wealth from the Middle Classes and moving the up to the 1-5% richest in the US and you will get that depression to clean/balance that all out there. The US is a consumer economy and the Middle Class in the US is Directly/Indirectly the creation of the Labor Movement in the US and there's no getting around that fact in the history of the US. The US has been in a New Gilded age since the 1980s and that's about ready to begin being turned back towards being more Labor Focused and moving the Tax Burden back onto the Corporations and off of the backs of the Middle Class that are not really Middle Class if one looks at the cost of Living currently!
