Answer: money is added to our economy through spending.
A liquidity crunch is a business condition that results in having too little cash and other current assets to be able to pay current liabilities as the liabilities mature. A liquidity crunch is a timing issue: not having enough liquidity can force you to make an emergency borrowing at a less than favorable interest rate.
Dividends are payments to the company by the shareholders.
Treasury bonds have lower rates to be more lucrative to buyers
A budget deficit is when the government spends more money than they are taking in.
A budget surplus is the opposite, the government is taking in a lot of money and is spending minimal.
the largest component of GDP is personal consumption
