It’s not age discrimination, it’s free market action. Older people want far more money and are far more costly especially where health coverage is obligatory. If they have not used their time to develop superior skills to offset those costs then it is uneconomical to hire them.
But they are willing to work at Walmart just to get employed! Don’t think they are pushing for the bigger salaries, ha. Many 50+ would be the best employee possible. But the country is full of screwed up thinkers doing the hiring now.
Have fun with your druggie work force!
