Test prep accounts for a small portion of test score differences and minorities are more likely to use test prep.
We place faith in effective political and social institutions and aggressively defend them from those that attack them or bypass them.
The tax rate is what matters there not the total tax. Similarly, look at the emissions per dollar not total emissions. If you care about monetary inequality, complain about that directly, don't drag global warming in.
When one considers the hidden costs of increased urban sprawl, reliance on automobiles, and the associated increase in pollution, it isn't so clear. If roads were privatized then the true costs would be more clear.
