Yes, the leak was illegal, but it's something the American people should know. I contest that they should know this because these billionaires have real power over our government, our commerce, our news, and our economy. If there was some mechanism that allowed for someone to not ever amass this much power, then I would agree that it's wrong to leak this information. However, if these billionaires are off shoring money to avoid paying taxes, or using the tax code itself to their benefit (the same tax code that the senators that these billionaires were giving direct and indirect campaign contributions to revised from the Obama and Trump eras), then I think the American people should know about it. The official narrative is that the top 1% pays more than it's fair share, but if you look at the numbers, these billionaires are claiming that their income is, things don't add up:
The latest IRS data shows that the U.S. federal individual income tax continued to be progressive, borne primarily by the highest income earners.

I'm going off of the table with the incomes and it shows that of the 1,443,179 returns from the 1%, it claims that they made (adjusted gross that is) $2,420,025,000,000 for all of 2018. If you divide the money by the number of returns filed, you get an average adjusted income of $1,676,870.99, or approximately $1.7M as the
average income of the top 1% in this country. This is definitely not correct. There is no way that Elon Musk, Warren Buffet, and Bill Gates can be in that bucket and only rake in $1.7M in income in one year. Sorry, not buying that. And yes what they do is legal, because their main strategy is to take out loans that are higher than their incomes and make business decisions to do things like not pay out dividends--thus decreasing their capital gains tax while increasing their stocks thus giving them collateral for all of the loans they are taking out.
So if these very rich individuals are giving dark money to candidates, helping to appoint people to political offices like the IRS, the FDA, NSA, CIA, FBI, ect. and promising them jobs or speaker gigs when they leave office, then they have more power than you or I, and they need to be held accountable for this vast power. This leak just proved what most Americans suspected, that the rich get out of paying their fair share of taxes, and they do it through legal, but questionable avenues, that are only available to the ultra rich. This realization is just another piece of evidence of the erosion of our democracy. It tells the world that we are for sale to the highest bidder.
