It matters to the employer who pays them and gets negatives instead of positive for his time, cost, and effort. It also matters to you who will pay more for all goods and services because the drop in productivity will raise prices across the board.
If anything it will give them the healthful motivation to improve themselves by trying for something better. This is the way it's always been, and it doesn't matter if anyone likes it or not.
You have either been out to pasture too long or on Mars to think that things are the way they have always been. Does giving them free schooling motivate them to better themselves? Does giving them free healthcare motivate them to better themselves? I am talking about Americans, not illegals.
Does triple pay and lots of time off and loafing on the job motivate the unions? Does 90% pay while sitting idle in a "job bank" for months and years motivate unions to improve themselves? Does a year and a half unemployment pay motivate them to help themselves? Does free housing motivate them?
You and I are talking about completely different people. The only thing that motivates people is fear of pain and hope for pleasure. The left has removed the pain from failure and the pleasure from success.
That is what we are looking at today, not the way it was 50-60 years ago.
