> They care about
wages generally in that any wages growth has an effect on investment returns. So they oppose wages growth, and if that means an increasing wage gap that is fine.
There is no reason to think that wage growth negatively impacts investment returns in general. It requires employers to pay more but it also means that customers have more money to buy your products. For legislation that applies to all employers, wage growth is generally a net positive for investment returns because it grows the overall economy. People buy more stuff when they have more money.
The real problem is when industries get specific carve outs, which they do have the incentive to lobby for because most of your customers are not your employees, and the business won't lose as many sales to their own employees as they benefit from paying lower wages, as long as their other customers' employers don't get to pay lower wages too.
Doing that actually harms investment returns on net, because the harm to businesses across all industries lost from your employees is more than that specific industry gains from paying lower wages. But it's the same problem as avoiding pork barrel spending -- one industry will fight much harder to take a billion dollars off the table than everybody else will collectively fight to avoid losing fifty dollars each, even if fifty dollars times everybody is significantly more than a billion. So then that happens over and over and adds up to real money.
