Conservatism, by definition, means going with tried and proven ways of governance. What those are depends on the culture and history of the region or country.
You appear to take a critical position on Conservatism. Take a look at what American Conservatism is about and it's level of success before judging. American Conservatism believes in equal opportunity, equal justice, individualism and charity. It holds in great reverence the Constitution and it's ideals of limited federal government and natural (individual) rights. Individual rights are those inherent in the people and do not need an outside enabler (like government) to make them work. It also believes in the power and ability of free market principles to make everyones life better. Although these are principles on Conservatism, it is also pragmatic to bend to a certain extent to non-Conservative principles that may already be in place. For instance, Social Security, Medicare and Medicaid may be over-steps of limited Federal government, but they are willing to live with them and just reform them from the bloated, bureaucratic, wasteful mess they are. Neither would it want to go back to the pure market-driven, exploitative days of the Industrial Revolution. Conservatism has no problem with natural inequity in life, just as long as individuals are not blocked or impeded in their rising above those inequities. The implied Constitutional mandate of the proper role of government, being the protection of rights and liberties of it's citizens is the mechanism that support this. This does not guarantee happiness, but it protects their pursuit of it. The individual's abilities are what determines how far they can go. For those who have difficulty, there is charity, even a hand-up from government to a certain extent, but not a handout. Compassion is not measured by how many people can be taken care of by government, but by how many DON'T have to be taken care of by government, trapped by welfare.
