on that (M+C)V=P Q thing where C can cause an increase in prices.... increases are to P or Q, depending of if output is near maximum or not...
Either prices or output would rise. If demand is low, then output would rise; and, with it, employment. If demand is high, and employment low; then prices are a function of the amount of money that is available to flow through the economy. As the spendable income rises, so goes the money flow in exchanges...
let
Meff = M+C (Money + Credit)
Qeff = QD + QF (Domestics + Foreigns)
then
Meff V = P Qeff
If the "rich" have a lower "Propensity to Spend",
i.e. they spend "less money (
M -> M), less often (
V -> V)"; then they "siphon off" Money, from the consumer economy,
i.e.
M V ---> M V
If so, then the "rich" exert downward pressures, on Prices & Quantities
(of existing Products, i.e. Goods & Services):
P Q ---> P Q
savings only leads to lower prices as demand falls and prices fall... This is the process of deflation... savings can cause deflation by reducing demand which leads to falling prices
Then "entrepreneurs" would try to "tap latent demand", by "innovating" novel Goods & Services, catering to "rich" clientele:
luxuries, e.g. "wine"
Investment advice, e.g. "Bernard Madoff"
I.e. our economy needs
(non-Criminal) "entrepreneurial spirit" (not "Taxes"), to "reach untapped Demand":
While savings equals investment, it only equals investment when there is market demand to be leveraged such that there is a demand for investment... savings equals investment which increases output to reach untapped demand
Lowering taxes to increase spendable income only works when the economy is at less then full output. Eventually, prices rise to consume all available income then we are right back to where we were, except with less tax revenue.
citing Frederic Bastiat, you have observed half of the economic effects, of "lowering taxes". However, with lower Taxes & higher Prices, the latter incentivize evidently-desirable expansion of Production output capacity
(otherwise masked, by the burden, of taxes, which compete against market Demand).
Ergo, Taxes dis-incentivize Investment
(by dampening otherwise-evident economic indicators, of excess Demand).
Since the recession, the demand for imports has fallen to 50% of what it was... excess demand doesn't exist. At first, when the recession occurred, demand collapsed on the collapse of consumer revolving credit.
i.e.
C --> 0
Meff --> Meff
Qeff --> Qeff
QD --> QD
Some of the recovery has been on an increase in the use of credit. In this case, the increased use of credit triggers increased output. (and some of it in China, which is pissing some people off.)
i.e. the reverse, of the above (as more Money is spent, on more foreign imported Quantity)
