As colossus pointed out, technology advance is not associated with Unemployment. Malthus argued upon scarcity, but he has been proved wrong. As you hold an undergraduate economics degree, you might already know that economics "best friend" is history.
There's no reason to talk about a future technology boom, as we have already experienced it. There's not any similar technology boom in history from that of 20th-21th century. Not even close. Also, Marx has been proved wrong on this subject. Austrians have worked extensively against Marxist Theory (most notably F.A. Hayek and L. von Mises).
About the political tendencies and the left. After WW2, Greece and Korea suffered a civil war between communists and non-communists. Koreas' split is well known, but people do not know much about Greece. In Greece the communists lost, but the implications were tremendous. Left parties (socialists) abused communist ideals and they deindustrialised the economy. Also, they created class conflicts and massive statism was in favor. They created an economy full of rigidities and inefficiency. They gave tremendous power to unions and they abolished any concept entrepreneurship. Some Greek quick facts:
- Greece extracts top quality olive oil, better than Italy (except Sicily) & Spain but it cannot export since there is no factory to put it in bottles.
- The only industry that operates properly is commercial shipping (1st in the world), because it has nothing to do with Greece as the most shipping companies are off-shore.
- 1/10 of population (NOT labor force) works in the state
- Specialized young people work as delivery boys etc because there are no industries to give them work.
- Unions have the right to blockade or use violence anytime they want
- Greece's GDP before crisis was that high due to consumption (i.e. AE) and there was not any Investment.
Conclusion
Are the left parties the right way to go in first place? Democracy by its nature gives more power to lower classes than upper ones. What will happen if there is a party that is willing to redistribute blindly just to keep happy only the lower classes? We all know that upper classes have more political influence than lowers, but if a party achieves to keep happy the lower classes then they will vote them again and again. Therefore, here's a spiral where the government manipulates the masses to vote them, the investors will leave as they will not afford to lose money, and competitiveness will fall.
