Speaking as a small business owner/entrepreneur myself, there are lots of tax deductions available to people like me that aren’t to some collecting a salary. And that’s without doing any of the borderline or outright illegal stuff that I see many other business owners do, such as taking fancy vacations, leasing luxury cars, or buying real estate for personal use but writing them off as business expenses. The IRS basically now lacks the resources to go after most such cases, and even if they’re caught, the penalty often just amounts to paying back the avoided taxes. There’s really very little incentive to play by the rules. I’ve had CPAs tell me outright that I’m leaving money on the table by not using some of these so-called tax minimization strategies. Anyway, it’s all kind of beside the point because “tax the rich” as policy covers so much ground that it’s impossible to discuss the pros and cons without specifying what specific proposal we’re talking about. My point is simply that business ownership and entrepreneurial activity are already quite well incentivized/rewarded by the current tax code.
