The Wikipedia article you linked to doesn't support the assertion that Government spending should be less that 30%

And in-facts disputes the claim that lowering US tax rates would actually increase the tax take

We actually have the evidence to back this up as the deficit grew when Trump cut rates

> Why it is more effective to limit taxes, because by definition, private business is most effective form of production, and gov't entities are least effective form

This is also an unproven assertion as there are plenty of examples effective public spending and ineffective private production

> effective public spending > ineffective private production

You really thinking, if private company will be ineffective on concurrent market it will survive significant long time?

And you also thinking, exist some superhero, who always stopping ineffective public spending?

I think, you just manipulate, showing rare cases as typical practice.

And yes, I agree, could be exceptions, but I said about typical cases, because we cannot lean country on rare things. Country should have concrete reliable foundations.
