Of course it did. The question or debate is not if unconditional money helps, but if it's better than alternatives which may be cheaper, such as food credits. Even middle class people would benefit, like $750 to buy groceries. Inflation obviously will erode some of this new purchasing power.
The government is very good at giving people money. It's less good at adjudicating whether people require that money. Replacing every government assistance program with direct, unconditional cash transfers would almost certainly be cheaper than the bureaucracy that must be maintained to ensure only "deserving" people get assistance.
But devil's advocate: is there any reason the same outcome couldn't be accomplished with a negative income tax instead, leveraging a bureaucratic infrastructure which already exists and isn't going anywhere?
