For a valid experiment, the term should be a control variable on subjects:

- 0 years (ie no income, as per current)

- 1 year

- 5 years

- 15 years

- life

For example, it's possible subjects knowing they will get zero or one year of BI could have better outcomes than ones who know they have a lifetime of BI. Or not.
