By not existing I meant alternate jobs from the private sector wouldnt exist

Rather than the actual positions.
The problem with keeping the money in people's pockets is it will build up in fewer pockets instead of been spread out amongst more people, that will cause a weaker economy because ultimately no matter how rich a person is they will only buy what they need for themselves, they wont buy it twice just because they richer. A nightmare scenario for a government I suspect is people hording cash in bank accounts just saving it for a rainy day, whilst that is prudent it is actually a killer for the economy. Probably why conditions have been manipulated to make that unattractive.
