Raising the corporate income tax rate would reduce economic growth, 

no it wouldn't.

and lead to a smaller capital stock,

ok, but nobody cares.

lower wage growth,

bullshit.

and reduced employment.

employment is determined by demand, not by taxation. if you cut taxes on consumers, you increase demand, leading to more employment. corporate tax rates are not a meaningful input variable, here.

Under a higher tax rate, some investments wouldn't be made, which leads to less capital formation, and fewer jobs with lower wages.

that's bullshit. investments are determined by projected returns, and interest rates are 0%. it's just scare mongering nonsense.

the types of arguments that i will accept have to do with waste. you could argue that corporate taxes pull in less per dollar circulated than consumption or income taxes, and be right. but, you're not really embracing mmt, if you're arguing that point, you're still thinking in terms of the gold standard. conceding that corporate taxation is less efficient, you haven't provided a reason that we ought to seek efficiency in taxation. if we prioritize other concerns, we can come up with good arguments to base the tax system on corporate profits, rather than on labour earnings, on property ownership, etc.
