What are Trump supporters thoughts on his refusal to pay American workers/companies?

Trump has a habit of not paying his workers and contractors. He has 24 violations of the Fair Labor Standards Act since 2005 for failing to pay overtime or minimum wage. He also has 200 mechanic’s liens since the 1980s. Records released by the New Jersey Casino Control Commission in 1990 show that at least 253 subcontractors weren’t paid in full or on time. What are your thoughts on why he refuses to pay? Surely they can't all be for subpar work.
