So here you have the dilemma of selling free enterprise. The difference is between utopians making promises, and free enterprise offering only opportunities. Promises are guarantees, opportunities are only choices. That utopians have not once lived up to their guarantees seems to be missed here. That utopians deliver only bureaucracies, limitations, and scarcities is always overlooked.
Free enterprise offers mere choices.
You don't have to take up an opportunity. It's there if you want to work toward it. That's the real difference. Free enterprise allows each individual the freedom to choose. It is a system in which you can have, not one utopia, but as many utopias as you have people to create them.
