Its true that stimulus is by definition a redistribution of wealth via (allegedly) future tax revenues going to the stimulus recipients.
But that is only part of the story.
First, there is value in short term injection of capital into the hands of consumers so as to keep demand sustained for food, energy, and all sorts of consumer goods. If stimulus is not done, and recession occurs (or deeper recession occurs) then that costs the people who would otherwise complain right now about stimulus perhaps even more.
Second, the people who now might complain about stimulus sure did advocate for it to business interests, such as banks, in the 2007-8 timeframe, and with the same argument in reverse: support us now with what is essentially a loan against future tax revenues so we can keep paying you a salary for your job.
The wisdom of it depends on which side of the ledger you are on at the time, it would appear.
