The republic of Texas exhausted from 1836 to 1845 before Texas join the United States besides the likelihood of war with Mexico why did annexation take so long?

Texas practiced slavery, and the US already had adequate problems maintaing a balance between the north and the south on that issue. Texas had made an effort to go it alone as a Republic, but it lacked recognition by most of the world and had created an enormous burden of debt. Texas needed a handout in a big way.

yes they have. but is this a true false question? if it is, the answer is true.

health care plans in the united states having high costs because they are focusing on providing quality programs for different groups of individuals. the quality of the service is based on money flow received from the members. without this investment, couldn't be possible a constant scientific searching to prevent death and illness caused because of low levels of health investigation. currently, the complaints are not about the highest cost, but about the coverage and benefits to access the necessary health services required by the members.  

besides, if a global health system is established the quality levels will fall down because of the standardized of the health. the access to care will increase but the quality will be low because it depends on the money invested.
