What's the use of paying taxes to a corrupt government that wastes your money and doesn't represent your interests? Tax evasion is symptom of deeper problems in this case, not a root cause.
The government did not waste the money, it gave too much to too many railroad workers, civil servants, teachers that now protest against the government that gave it money it didn't have in the first place.
And no, debt is not the root cause of tax evasion, tax evasion results in less money for the government so it borrows more and takes on more dept.
