Actually, you are 100% correct! However, it wasn't the "free market" that created the commodity glut, but rather…you got it…permanent Keynesianism:

The Communist Manifesto on the issue, 35 years before the birth of Keynes:
Modern bourgeois society, with its relations of production, of exchange and of property, a society that has conjured up such gigantic means of production and of exchange, is like the sorcerer who is no longer able to control the powers of the nether world whom he has called up by his spells. For many a decade past the history of industry and commerce is but the history of the revolt of modern productive forces against modern conditions of production, against the property relations that are the conditions for the existence of the bourgeois and of its rule. It is enough to mention the commercial crises that by their periodical return put the existence of the entire bourgeois society on its trial, each time more threateningly. In these crises, a great part not only of the existing products, but also of the previously created productive forces, are periodically destroyed. In these crises, there breaks out an epidemic that, in all earlier epochs, would have seemed an absurdity — the epidemic of over-production. Society suddenly finds itself put back into a state of momentary barbarism; it appears as if a famine, a universal war of devastation, had cut off the supply of every means of subsistence; industry and commerce seem to be destroyed; and why? Because there is too much civilisation, too much means of subsistence, too much industry, too much commerce. The productive forces at the disposal of society no longer tend to further the development of the conditions of bourgeois property; on the contrary, they have become too powerful for these conditions,
by which they are fettered, and so soon as they overcome these fetters, they bring disorder into the whole of bourgeois society, endanger the existence of bourgeois property.
The conditions of bourgeois society are too narrow to comprise the wealth created by them. And how does the bourgeoisie get over these crises? On the one hand by
enforced destruction of a mass of productive forces; on the other, by the conquest of new markets, and by the more thorough exploitation of the old ones. That is to say,
by paving the way for more extensive and more destructive crises, and by diminishing the means whereby crises are prevented.
My boldface highlights. Capitalist government's don't pursue Keynesian "solutions" because they don't understand that these will produce future crises, and they don't do so because of the clamor of an ignorant public for something to be done. They do it because if something is not done, the economic system would collapse immediately ... instead of being shored up for the next crisis.
Capitalism lurches from crisis to crisis not because of bad policy but because instability is a necessary condition of its existence.
