You have plenty of choices regarding your desire (not need) to patronize large corporations, Ray.
Unless you use only what you need, bare minimum, to survive, you are a voluntary consumer. Unlike taxes, the federal government does not REQUIRE you to shop for nonessentials. Those are all voluntary acts on your part.
Furthermore, the government does not require you to buy nonessential products directly from corporations. You could, as noted above, buy used products, which results in no profit to the corporations. You could also buy only natural products.
You're voting with your checkbook, Ray. And every time you buy a nonessential item your vote is FOR corporations.
In other words, you're a corporate stooge, Ray.
