That's easy. Paycheck vs investment/job creation/revenue inflow.
The person that makes $100,000 a year vs the person who creates 1000 jobs that pay $100,000 a year.
The tax system has been corrupted by politicians who have been bought by the rich and we have been conned into thinking that one type of income is somehow better than another.
That is a great statement, if you were running for office.
Now, I am not going to say that our system is devoid of flaws, or that it benefits certain types of businesses, sure it does.
However, some income IS better than other. Some income is generated through millions and billions of dollars moving through the U.S. economy, while other is just a paycheck from a 9-to-5 job.
