When the framers designed the US Constitution they did not give the Federal government much power so power was balanced between States and Central Government. But the Federal government has gained more and more power over time. At the same time, the States were restricted over the years, when the Framers did not imagine doing so.
Both of these situations can be good or bad. For example, making the States respect the Bill of Rights was a good thing when individuals had their basic rights stripped on a State level. So making only the Federal government respect the Bill of Rights did not make much sense.
At the same time, the Federal Government has shown much power that was not designed and showed a few issues over the years, especially with the Executive Branch that had in a few opportunities overstepped its powers.
