It definitely is double taxation. (1st level: corporation, 2nd level: shareholders).

But the point is that the owners accept double taxation in exchange for the protections of the corporate form, like a legal liability shield, treatment of ownership interests as capital assets subject to lower tax rates on sale, deferral of taxation of shareholders' allocable shares of the business' income (as represented by dividends), etc.

A corporate tax rate is good policy. The answer to how high that tax rate should be has split families and friends for decades. Higher corporate tax rates drive substantially increased R&D spending and capital investments (and it's not even close; its easily 4x-5x the amount invested when corporate tax rates are low). This apparent paradox is quite easy to explain: when corporate tax rates are high, corporations will increase their spending on deductible categories to reduce their taxable income, and thus the tax they pay. When tax rates are low, there's little to no incentive to due that.

The corporation and shareholders aren't the same entity. How is N entities paying N taxes double tax?
