Meanwhile the infrastructure is not exactly doing great in many places, and it seems doubtful that it would be doing particularly better with more taxes collected. Anyway, there's been a pretty clear trend towards not-less, even in just the last few decades (really, compare quality of services and infrastructure at revenues and debts in the 90s to now), without a clear sign that it's actually worth it or that more would make anything better. A fruitless 20 year war didn't help either.
