Well, if it's a consumer purchase or a service purchase, then some man or woman has a job to do to make it, package it, distribute it, market it, sell it to you.  There's like at least one person with a job involved in each of those steps.  If it's a service purchase, then again some man or woman has a job to provide the service to you.  Most likely that person is relying on other people and/or their goods to be able to provide that service.  An example would be the lawn mowing service you use -- someone has to buy the tools to mow and edge your lawn and someone has to run the equipment.  Another example would be hiring a professional organizer -- he or she has to evaluate your needs, purchase products to organize you (see the previous consumer chain of events) and then actually do the work.

What is the outcome of this spending of funds on purchases?  Money goes into the economy thereby benefitting more than just you since you are now supporting other businesses and their employees.

Now you say, but what if it's an investment.  Well, a similar thing occurs.  Someone has to help you with the investment, either a financial counselor or a website with information.  Both of those mean that someone has a job to do because he or she must be able to provide you with information to help you make a decision.  Whatever it is you are buying as an investment is providing jobs for someone since the business in which you are investing is either making a product or providing a service.  (See above chains of events for consumer products and services.)

You may be thinking -- yes, but this just makes money for someone else.  What about me?  Let's think a bit here. . .if you are helping someone else make more money by either purchasing a product or a service, then he or she has more money. . .which means he or she will spend it either on a product, service or investment.  All of this produces more jobs and puts more money into circulation.

If more money is out there circulating around, then more people can pay their taxes.  This all applies to companies as well and maybe even more so since they provide more jobs for more people. 

So, how does anyone reasonably believe that more taxes are a good idea?
