The power of compound interest works both ways. For the rich, It can mean a spiral upwards, as they can exploit the difference in interest rates of different investments to make profit. For the poor, it often means a spiral downwards into greater debt, more frequent defaults and ever higher interest rates.
It was meant to be a rhetorical question. But yes this is generally true. But they can afford the interest rate much less than rich people (poor people).
Ah, I wondered if you were serious or not. But yes, it's another one of life's cruel injustices that helps money beget money
What someone can afford doesn't necessarily affect the price.
What really affects the price is what someone's best alternative is. If you have no alternatives, you get exploited.
