Everyone who is not a farmer or a miner is ultimately a "middleman." Yes, even the tradesmen fixing cars and HVAC system, much less lawyers, bankers, and politicians.
Ultimately, is only the great bounty of the earth, giving us a surplus of food and raw materials, that makes human civilization possible.
14 I, the Lord, stretched out the heavens, and built the earth, my very handiwork; and all things therein are mine. 15 And it is my purpose to provide for my saints, for all things are mine. 16 But it must needs be done in mine own way; and behold this is the way that I, the Lord, have decreed to provide for my saints, that the poor shall be exalted, in that the rich are made low. 17 For the earth is full, and there is enough and to spare; yea, I prepared all things, and have given unto the children of men to be agents unto themselves. 18 Therefore, if any man shall take of the abundance which I have made, and impart not his portion, according to the law of my gospel, unto the poor and the needy, he shall, with the wicked, lift up his eyes in hell, being in torment.
