Financial sector > Agriculture
Well, duh, everyone wants financial products for everything, including agriculture.
Say 2% of the population works in agriculture. Well, there are a lot more car owners than farmers and car insurance is mandated by law. And that's just car insurance.
People getting phones on contract depend on the financial instruments the phone companies use behind the scenes. Farmers selling their wares on the futures market (which as Tim pointed out previously is not inherently evil) depend on the financial industry. Farmers getting loans for capital or livestock and seed depend on the financial industry.
