So, my legitimate question is, after all the robbery, a person, who doesn't pay taxes, is a bad person for the society or not? More likely I want to get answer from those whose countries have a model similar of European healthcare and employment insurance.
Yes, not paying taxes is illegal. If people do not pay taxes, the government's stability would be compromised. Let's not forget that taxes are the lifeblood of a country. We must acknowledge the reality that as employees, we cannot avoid paying taxes, as our income is readily visible and declared by our employers. Although everyone is required to pay taxes, business owners have a more advantageous position than employees. They can manipulate their financial records, avoiding detection for tax evasion, as long as they understand how to navigate the system.
In accounting principles, there's a concept known as tax avoidance, which is legal and mainly benefits companies, rather than employees.
Tax Avoidance Is a Legal Way to Limit Taxes; Tax Evasion Is Not
