It didn't become customary for presidential candidates to release their tax returns untill the 1970s.

Yes but then it went away for many years. It returned in the 1890s also. The current system that we know didn't start until 1913 thanks to the 16th Amendment.

Yes. . . and the current system is fraudulent to the core.

Nixon did it. I love watching the butthurt happen.

He sure did, though a little late. That still doesn't qualify as "everyone else before me". Also, Ford only released a summery and not his actual returns. Roosevelt didn't release his either. His presidential library did later though. Since Federal income tax became standard in 1913 only 8 of the 17 Presidents have released their tax returns while in office or running for the presidency. So basically, not "everyone else".

And, it's not a requirement. It's a voluntary action which all candidates know is coming so they often put all their assets into a family members account to make it look better.

If your tax return was 30,000 pages, you'd probably want to have someone go over it with a fine toothed comb if the media was dead set against you. If there was something illegal in there, the IRS will prosecute, I'm quite sure. It's their modus operandi.
