You are mixing several unrelated items together. We agree that there is an intentional dumbing down of the population. That is driven by...government intervention in the education market. The direct cause is government schooling. Let’s end the governments monopoly on education, both the physical act and the regulation of what is or isn’t an education.
Your intentions, however good, are misguided in the area of government subsidizing ‘museums’. Should they subsidize the museum of porn? Historically, museums were funded and sponsored by the wealthy. Let that be the case today. I like culture and am well educated in a classical education across great music, visual art and literature. I don’t need your confirmation of such, nor the financial subsidy of music, art or literature by government. No thank you.
To presume that culture will collapse without government intervention is to ignore the War on Culture that our very government is waging. The dumbing down of Americans is a direct result of governments culture campaign. I mean should we be subsidizing the Kennedy Center or would the K Street crowd be able to fund it themselves out of the spoils of politics?
Government subsidy in and of itself is not always bad, as long as the decision to subsidise is democratically controlled. A government subsidy of a porn museum would attract a lot of criticism and therefore, because the people rule (or should do) it wont happen. The fact that such things are conceivable is, in itself, evidence of an uneducated populace whose primary motivation is the satisfaction of their baser desires.
Many museums are still funded and sponsored by the wealthy, but in proposing that is the only way things should be done you assume these patrons dont have ulterior motives as well. A lot of these foundations and trusts are very liberal. Or have been co-opted by the left.
