This article is horrible because it confuses concepts 

the USBIG definition 

"The Basic Income Guarantee is an unconditional, government-insured guarantee that all citizens will have enough income to meet their basic needs.",

and their page in general talks about a mix of Basic Income (BI) and Guaranteed Income (GI).  Although the article goes to great pains to explain the difference between BI and GI, and claim that BIG is BI and not GI.  The above definition of BIG is in fact GI and not BI.

"unconditional" aspect of BI, doesn't mean there is no forms to fill out and no approval needed

"government-insured guarantee" is pure GI, because the implementation is to subsidize people up to an income level.  A guaranteed income of $15000 means that if your income from other source is above $15000 you receive no benefit, if your income is $14000, you receive $1000, and if your income is 0, you receive $15000.

Basic income of $10000 means that you receive $10000 no matter what your other income is.

I can volunteer to make the radical changes to this page to make BIG mean BI, or I can alter the Basic Income page to no longer point to this page.  I will do so in a few days, assuming no one wants to insist on reverting the changes.
