Tim Ryan 2020! Corporate tax rates in the US are too high imo. There also are too many loopholes but cutting the most obvious loopholes only gets you to 28% or so which still would be a fairly high rate. To really make a dent in corporate tax rates without increasing the deficit or increasing other taxes you'd need to look at things like the corporate interest deduction or border adjusting them but these measures would trigger a corporate war (and border adjusting corporate taxes likely is illegal under WTO rules).
Technically you could get around that by adopting a broad-based VAT to replace the corporate income tax and employer-side payroll taxes. In essence you would get a border-adjusted VAT with a large tax cut on wages to negate the effect of a VAT which looks a lot like the Ryan corporate tax plan (which looks a lot like a VAT with a wage deduction), and border-adjusting a "normal" VAT is perfectly legal under WTO rules. But doing that would likely hurt ordinary Americans unless it massively grows the economy (which is possible). Theoretically all the benefit of lower employer-side payroll taxes and 20-30% of the benefit of lower corporate taxes should go to households in the form of higher wages, but I'm not sure whether you can sell that to the public (let alone selling the idea that slashing/repealing the corporate income tax would help the economy).
Anyway, I do understand why some Democrats are frustrated by this. The idea of cutting corporate taxes probably doesn't match very well with an American liberal ideology.
Corporate taxes are a small factor. How much difference does a 25% or 30% or 35% rate make. Healthcare costs are a 100 times bigger factor which major countries in the world don't force their companies to cover. That is a huge HUGE cost difference. Healthcare cost is at a ridiculous high of 18% of GDP & is increasing.
It will be consume American businesses. Healthcare should be decoupled from businesses with a single payer plan & then you could with time deregulate some areas, adopt more private insurance etc & get to a more complex plan. Corporate taxes won't help a dime when it comes to employment when people have so low of a disposable income, there is so much concentration of wealth & when corporations are not at all cash starved.
