I’ll take it.
The government has modelled this very carefully, its not only about keeping alive and buying food.
They know that, as consumers, other businesses depend on us too, such as car manufacturers, clothes shops, bike shop, local gym etc. If we don’t have the money to spend then the economy grinds to a halt and the knock-on effect is quite big.
To the government, it’s not a gift but an investment. They know it will help keep the economy moving. If the local gym, hair salon, bike shop stays open it will continue to pay tax. Closed businesses (and unemployed workers) pay nothing.
