Answer:
They take money out of the economic system
Step-by-step explanation:
Taxes and savings decrease the net income of economic agents, which are households, firms, the financial sector, and the economic system as a whole. If there were no tax, the agents' income would be higher, ie, taxes are a leak of income that economic agents transfer to the government. Thus, if the government decides to use taxes, the money goes back to the economic system. However, if the government decides to save resources, the entire economic system experiences a leak.
