how a person gets paid for their work isn’t the issue. the greed of people who are financial well off but claim otherwise for some sort of benefit is the real problem in that example. in the end their salary would be hard to pay for them since they own so many things that have a monthly expense LOL. they should sell a car and see how much easier it is to meet their payments while on furlough 
Ultimately, the people who pay the most toward Tax and National Insurance, are the same people who see the least return for doing so. 1 person in the higher tax brackets ends up paying for the multiple people at the bottom of the hierarchy pyramid who use the services without end, despite not paying nearly anything towards the costs accrued. the result is less people are willing to pay that cost on another’s behalf.
it’s a matter of, the better off you are, the less likely you are to have issues that require you to use the service at all. I pay my NI and despite it not being much, I have never used the NHS for anything since I started working, so I am covering the costs of other people who go there with this weird mindset of “I paid for this so lets get my moneys-worth” when their costs amount to many times more than what they paid in.
uncertain markets when you work for yourself or as a small group definitely mean its safer to reduces the outright expenses when business drops, so getting paid in dividends just makes a whole lot more sense than giving yourself a higher salary and then a year comes along where you can’t collect that salary as you had no work
