If you get enough carbohydrates from a decent variety of unprocessed plant and vegetable sources, you'll get enough protein from those sources, too. Like Jak said, oats and other unprocessed grains are good, and cheap. Legumes are good, and cheap. If you try to subsist on simple carbs like sugar and alcohol, you will soon be protein deficient.
