that's not necessarily true though is it. first off the government has no issue creating money to bailout corporations, thus the money could be created/borrowed to pay for infrastructure projects and repaid over the long term. Secondly 'without them' would mean without the multi-millionaires and billionaires. Well if we didn't have them it would be because of a more equal sharing of the wealth, thus the same tax revenue could be gained from a wider share of the population. The economy has the same value/size it is just currently concentrated in the hands of a few, there is no reason it could not be more equally spread out, except that those with money, get to buy those in power and lobby for rules that make them richer and make it harder for people to compete with them.
