Because the phase out of the stimulus begins at $75k for individuals, and goes to zero at $99k. That level of income is not exactly uncommon in Connecticut where to make the top 1% you need to make over $750k/year.
The "average" is, of course, highly skewed by some extremely wealthy households at the top. The use of an average number may not provide an accurate picture of the poverty in our state. In 2019 the median US household income was about 63k, while the average was almost 90k. Yet last year a Treasury survey concluded that 40% of Americans would have difficulty raising $400 in an emergency.
There are 84,600 households in Connecticut that don't even have a checking or savings account (CT Mirror, March 2020). There's got to be many, many more CT working poor and lower income households for whom this money may be really important. For many in Connecticut, the aforementioned food banks and soup kitchens are a literal lifeline.
I'm feeling very lucky that we still have an income, a secure home and the ability to contemplate where to apply our small piece of stimulus money beyond our next meal or to keep a roof over our heads. So many in Connecticut and all over the country do not have such options.
