are you suggesting that eliminating carried interest would deter private equity from bothering with small businesses, and make the remaining small businesses feel like a more reliable thing for workers and employers to engage in? because they won't get shuttered unceremoniously?
if I'm understanding that correctly, I have to giggle, because there are plenty of ways for institutional money to have lower taxes than ordinary income tax rates. waaaay lower than the carried interest "loophole".
also, to me, loopholes are unintended things that no one person in government or branch of government noticed. like a couple of private letter rulings from the IRS combined with an accounting tweak in a budget appropriations bill. carried interest isn't one of those to me when it was directly passed by congress explicitly and deliberately affirmed multiple times in subsequent legislation.
but I could be misunderstanding your post entirely.
