Limited capitalism is a right of democracy to choose for itself as we the people:   what our limits and boundaries shall be, in terms of possessions, property, or influence upon our lives as a society.  By limiting the money to no more than a defined amount, more than any other person.  For simplicity we will call that 3 times more than the lowest paid “40 hour worker”.  Thereby the average worker gets double the lowest paid worker/ but the lowest paid worker gets not less than one third the highest paid worker.  All personal income is for a worker/ nobody gets to call themselves something else.
Business income is separate, and untouched by governments until it is clear they have attained more than their investment.  Even then what is taxable is what is taken out for personal income.  Anything beyond that amount goes to the bank for loans to the community; unless it is declared to be spent for the business.
Limited capitalism is the right of the people in democracy to say to each other: THAT WE SHALL ALL, have a chance to share in the benefits of this society/ because we refuse to let any individual attain more than the limit on income or the boundary we set for personal property or control of property or any other form of power over us.  We will control our right, to share honestly in this nation;   by limiting the money to what is fair for us all.  Or, you can earn that income in a day if you wish/ but you cannot earn any more until the year goes by; so that the rest can obtain their share.  If the community allows it: you can teach your competitors (community decides who), and thereby obtain a little more if you do it well.  By vote we decide what the limits and boundaries will be/ with a return vote to adjust as necessary. 

This is in fact “completely constitutional” and fundamentally demanded by the constitution itself, in its preamble;   the agreement of this our nation.  Do read it.

“We the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquillity, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and to our posterity, do ordain and establish this Constitution for the United States of America.”
