They also have benefits that W2 employees do not, like deducting expenses, $50k+ in allowable retirement contributions per year, and the 20% QBI deduction.
It pays to keep in mind that in order to deduct an expense, you have to pay the expense. So as a freelancer, when I pay for my computer, that's $1500 out of pocket. Then I don't pay quite so much in taxes. But I've still got $1500 less at the end of the year than if I worked at a business and they were paying for my computer.
$50K+ into your retirement is also great, but it's most useful for those who are making so much money that they can afford to put that money away and not touch it until they're 62. Some people can certainly do that, but I doubt that it's very common. Even FTE often don't max out their 401K. Here's a fool article that claims the average is rate is 7%: https://www.fool.com/retirement/2017/01/15/average-americans...
If you aren't able to max out your retirement account it means your QBI deduction is larger.
As with most things business/tax related, there's a lot of grey area and nuance here.
Maybe if you turned around and resold the system immediately. But I'm not gonna pay 1500 bucks for your 4 year old 133t machine that you spilled coffee and sneezed on.
