The spending of second stimulus coming from the government would depend on the recipient himself for we differ on socio economic status in the community which means we do have different needs and that will vary on how we will spend the second stimulus check. For the people that belong on the lower classes or the poorest of the poor, surely they would spend it to provide their necessities. For those in the middle up to upper class, it depends if they will use it for investment or purchase other things that concerns their necessities.
Here in our country where I currently reside, we do also have same program which is giving financial aid to support the directly affected individuals mostly for the sector of the poorest of the poor and what I can see, most of them used it for the sake of survival on which they primarily used it to purchase their necessities to survive the pandemic due to lack of source if income amid with the existence of pandemic. Here states that the expenditure of the stimulus or the financial aid depends on the individual based on the needs they needed to fulfill.
what more can i say? lucky for those who don't really need this money to survive. and more then likely they will just spend it to unnecessary things. but $1200 is actually not big amount, in reality, this amount will just be spent unnoticed. food and basic things alone with the added bills - that money is actually not enough to cover all those expenditures but will just lessen some financial troubles.
