Well, sort of. It does indirectly create jobs for financial advisors who buy/sell said shares for their clients. I was one for a couple of years, and I have family members with careers in the field.
My broker handles somewhere north of 1 bn in assets. He makes probably 1.5% on transactions less his overhead and staff. He is a frictional cost of business and his 5 employees make less than my top 5.
I see no reason why that sort of job creation should save investors on their taxes.
Their reward is the potential return. His fees are the costs associated with investment.
