That has been talked about 200 times in this thread. I'm tired of people entering a thread late, and oblivious to everything in it. So instead of you doing a bit of work of reading the thread, I'm supposed to do the work of answering this.
And what a frankly dumb question. If you own a business selling non necessity items, and your customers now have hundreds of dollars less per month to buy your stuff, what do you think is going to happen to your sales ? Duh!
So what is there to stop this situation ? Really nothing other than what Biden is proposing - a cap on housing rents.
I'll repeat post # 103.
This is not hard to understand. If one year, you pay $600/month in rent. A year later, you pay $1000/month in rent, and a year after that, you pay $1600/month rent. You now have $1000 LESS every month to buy the things businesses are trying to sell.
You have $12,000/year LESS to do that. There goes your plans to buy that nice $12,000 violin. There goes your plans to outfit your home with new furniture. There goes your plans to get that low miles 2021 Kia Forte.
And there goes the chance for the sellers of those things to sell them to you.
