Also, countries are in no way like families. It's counter intuitive but has been shown many times, e.g. paradox of thrift.
Can you show it to me ? What is the paradox of thrift ? Here is your counter argument :

Here you go from the start of the wikipedia on it:
The paradox of thrift (or paradox of saving) is a paradox of economics, popularized by John Maynard Keynes, though it had been stated as early as 1714 in The Fable of the Bees,[1] and similar sentiments date to antiquity.[2][3] The paradox states that if everyone tries to save more money during times of economic recession, then aggregate demand will fall and will in turn lower total savings in the population because of the decrease in consumption and economic growth. The paradox is, narrowly speaking, that total savings may fall even when individual savings attempt to rise, and, broadly speaking, that increase in savings may be harmful to an economy.[4] Both the narrow and broad claims are paradoxical within the assumption underlying the fallacy of composition, namely that what is true of the parts must be true of the whole. The narrow claim transparently contradicts this assumption, and the broad one does so by implication, because while individual thrift is generally averred to be good for the economy, the paradox of thrift holds that collective thrift may be bad for the economy.
So this is a good example of how national economics is different from family economics.
I am sure you can find better critisisms of this proposition in the literature, but let me try:
There is a fundamental error, and there are errors in the predicted consequence of saving. The fundamental error is that it does not matter. Every individual can do with his money as he sees fit, including saving them for later. The effect on the economy, or the greater good, is of no relevance to rights. A right to dispose of your property trumps everything, that is why it is a right. So the fact that it can have adverse effect on others, is of no importance. What Keynes here says, is that somebody else can better take care of your money using monetary intervention, that means taking away rights, and declaring that there are two sets of people, those who are masters, and those who are serfs.
The remaining arguments are the effects. These are secondary, due to the fundamental rights proposition, nevertheless there are effects. Every economic decision you make and act on, affects every aspect of the rest of the economy, albeit marginally. So if someone saves, that does not make a whole lot of difference, and if someone else spends, or reduces his savings, to the same degree, the effect of the total is even smaller, but not nil. This is normally the case, because saving is tied to the different stages in life that everybody goes through. The interesting question is when a large portion of the actors starts to save more at the same time.
There are different effects depending on the availability of sound money, and if the form of the saving is in money or in investments.
If we have sound money, and a large portion of actors starts to save more in money, the first effect is that the value of the money increases because they are bid up, which is the same as prices of goods goes down. This is really the same thing. The savers reduce their consumption, that is what saving is and that is why they accumulate money. The prices of goods will not all go down at the same rate, the consumer goods will go down first, and capital goods least, which is ok because point of the saving is to spend later, and the businesses will focus on producing for the future, so capital will go to the earlier stages. Since consumer prices go down, the non-savers can consume more.
If we have sound money as before, but most of the saved money goes to investments, or indirectly to deposits in savings and loans institutions (old fashioned banks), the interest rate will go down and the investments can increase, so the effect on the capital structure is increased investment in general, and a change of the capital structure to the earlier stages. This means a capital structure well adapted to the expected later consumption, plus general increase of investment which increases productivity and therefore the ability for all to consume more. This will be the normal situation, because the savers will first secure their position with the safest asset (the money), after that they will invest or lend to get profits or interest. You see that saving generally is positive both for the saver, who acts in his own interest, and everybody else. In fact, saving is a precondition for a prosperous society.
What the monetarist will do in this situation, is to expand the money volume either directly or through lending out money they don't have. They will expand the consumption in the government, and they will reduce the interest rate down from its natural level (expanding money supply and reducing interest rate depend on each other). The adverse effects of this are plenty, everybody knows the transfer of wealth from the savers to the spenders. Somebody gets the new money first, the cronies, it's bad in itself. There is also waste in government spending. They can not spend the money as well as individuals in the free market, due to lack of pricing information. Government spending is a negative sum game. The worst effect, is the wrong signal the low interest rate gives to the market. It signals to the public to spend, to loan more for spending or postpone downpayments of loans. The public will bid up the consumer prices. The low interest rate, as before, will signal to the capitalists to invest in the stages of production most remote from consumption, like oil rigs and surveying for minerals, which is supposed to return way out in the future, while the spenders consume now. So everybody is happy for the new money, while savings halt, and therefore capital is eaten up, and the wrong investments are started. This leads to destruction of value down the road, and crashes in market, the new word for that being turmoil.
Basically, to intervene in savings using monetary politics, is wrong on all accounts.
