Supply-side economics from which trickle-down has been coined refers to the disposition of profits or retained earnings themselves. It proposes that apart from the obligations you are calling out, that your judgement with your profits will further benefit people like your staff to the same or greater extent than robin hood style government policy.The idea that the interests of employers are aligned with the interests of employees is trickle-down. Its a term that's been criticized, but there's validity there.
With all due respect, Antagon...I don't think you're correct. By law employees receive pay in return for their providing labor to an employer. The employee will receive that pay whether or not the business realizes a profit from the investment that an employer makes. There is no "trickle down" taking place...it's ALWAYS "trickle up". As an employer I'm constantly controlling my costs trying to realize a profit. I don't have the luxury of telling my employees that they will only be paid if I make a profit. If I do I'm going to end up in court or worse in jail.
My point is that I still don't think that there IS any such thing as trickle-down. It's a straw man. It's always trickle up. The term trickle-down was coined by people that don't understand economics because the expression made it appear like employers had the money all along and decided who was going to get it after they'd taken their profit out. That isn't the way things work.
