just the opposite. 
I agree with taxing this, but it should ALL BE TAXED AT THE SAME RATE. 
It is insane that politicans change it up. Money is money is money. 
SO, 
if you make 100K from a salary/wage, then you should be taxed $X.
If you make 100K from a Lottery, then you should be taxed $X.
If you make 100% from capital gains, dividends, etc, then you should be taxed $X. 

What is needed is to make taxation fair by simply saying that if you get $ from a source, ANY SOURCE, then it will be taxed in the same way with NO BREAKS, DEDUCTIONS, OR EXEMPTIONS. 

THis is the only way to not only keep it fair, but to stop CONgress from paying off their friends.
