Washington politicians lie all the time. They all know "deficit spending" is never a problem. Not with our constant revolving door treasury.
The US government really does have an endless supply of money. It never stops. I don't know why Washington bothers with the ruse of a budget anymore. It can be spent twice as fast as it come in and there will never be a problem - until it stops. As long as the economy is growing, it will never stop. That's the only crack in the system.
Politicians use "deficit spending" warnings as a way to control the masses, or to try to get the masses to vote a certain way. They know it is something people can misunderstand because the people have the knowledge only of their own money in their lives. Joe Sixpack's money always stops with the last digit on the last paycheck. Joe doesn't get an hourly influx of money like Washington. Joe really does think Washington is just like him and has only a certain amount of money to "live" on. Joe doesn't understand the tax and spend revolving door at all.
That's why Washington gets away with the lie.
