Debt crisis affects capitalists, self employed, middle income and everyone.
It also affects GDP directly and trough business confidence which annoys capitalists indirectly.
Taxes also affect GDP, self employed, middle income and capitalists.

UK would take most of time to do so since it has by far fewest policies.
Socialist playtrough would have advantage since you are reducing amount of capitalists, middle class and self employed anyway.
