I'm not a political science major or an economist, more a salt of the earth type but even a Joe six pack like me can plainly see that the bigger government gets, the more the economy suffers (meddling regulations, higher taxes). The bigger the unions get, the more the economy suffers (employers forced to shift production overseas or cease operation altogether).
The smaller government is, the better the economy is (less meddling in markets, less taxes, more growth). The smaller the unions are the better the economy is (more competition, companies can afford to invest in growth and expand, hiring increases). Smaller government means less social programs (removing the yoke of social programs stimulates incentive and motivates more to join the work force or start small businesses, increasing the tax base and decreasing the burden overall).
All I know is when more people are working and contributing to society as opposed to large numbers of people out of work and on the public dole things are better all the way around. People who earn their own keep have an awful lot more self respect than career welfare cases. People who own their own homes know the pride in that as opposed to those who rent and blame their landlords for their station in life. It translates into better communities with less crime and abundantly more civic pride. A man who earns his own keep and contributes is a citizen. A man on the public dole is a serf. Idle hands are the devil's workshop.
