The whole point of mixed model economics is to have parts of the equation in place that throttle the other, to apply the economic understandings of balance between market and planned economics. Ideally have monetary, fiscal, and trade policy that reduces the amplitude of the economic cycle for a more consistent growth pattern in the long term and escape the idea of bubble and pop economics. We know from study in this area of academics that on a long enough timeline strict capitalism is just as likely to destroy itself as strict socialism, so you apply principles of both as reason to balance the other.
