Careful with drawing too many conclusions from that. I’m not sure I understand why, but many corporations have open positions advertised that remain open for very lengthy periods of time, to the point that I wonder if there is any intention of filling them, or if the jobs actually exist at all. Governmental job listings are notorious for this.
I’m sure some of them are those work from home “jobs” too. But I did put in my local zip code and I know most of them are available because I’ve seen them on the DOL and other local sites/newspapers. Whether it’s 2 million or 3 million, the point is there are jobs out there and many aren’t even advertised on these sites. I see too many people who are of the attitude of “I’m too good to do that job”. But when times are tough, you do what you gotta do.
