It is not increasing the economy, since government spending tends to rely on borrowing to fund the spending above the money taken in. And the debt repayment will eat up the budget in the future.
Short term, depressing interest rates paid out today because of federal manipulations to NOT pay higher interest rates, hurting saving and investing.
And the increased government and spending does not help economic growth - as we can see with the massive bailouts and 2008-2012 spending binges now petering out.
More spending by the feds is not the answer - cutting back on financial transfers that lead many to stay out of the workforce, eliminating a lot of regulation that hampers business growth and ending the economic uncertainty of the feds trying to fix everything would help the economy.
