Or when a restaurant owner inexplexably has really low private food expenditure, or has really low revenue on paper despite being relatively popular, or small companies having a lot of company dinners, or labor workers having a lot of company places to go in their company porsche SUV, or...

The reason regular salaried employees do this less, limited to the kind of sort arbejde ("under the table" labor) you describe is because it has become obscenely difficult to do anything meaningful with sorte penge (untaxed money) - not because people don't want to do more or didn't previously do it.

Seems to me salaried workers would be a category that is more conscientious by self-selection. They are comfortable working within the rules of a system and less willing to take risks such as by violating those rules.

Yeah, but that there is such a distinction is a little sad. The use of companies for tax avoidance can also lead to some prejudice against small companies in general, which is unfair to those playing nice.
